Quick answer: "Can tab" most literally refers to the metal pull-ring on top of a drink can (soda, seltzer, energy drink) that you lift to open it. Separately, a TikTok trend has assigned symbolic meanings to different can tab shapes, exchanging a specific tab shape is meant to signal a specific friendly gesture (like a hug or a hand-hold), and can tabs are also popularly used in DIY crafts like jewelry and recycled fashion.
The literal, everyday meaning
Before any trend or symbolism, a "can tab" is simply the small metal ring or lever on top of an aluminum beverage can, the part you pull to pop the can open. This is the primary, most common usage in everyday conversation: "I bent the can tab," "save the can tabs for recycling," or "I lost the can tab and can't open this."
The TikTok trend: assigning meanings to tab shapes
A viral trend, particularly popular in 2021 and recurring periodically since, assigns specific social meanings to different can tab shapes, based on the shape of the small opening or notch on the underside of the tab:
- A semi-circle shape is commonly said to mean a hug
- A full or different circular shape is commonly associated with a kiss
- Other shape variations get assigned to holding hands or other simple, friendly gestures
The specific meanings assigned vary somewhat between different TikTok creators and posts, since this is an informal, user-generated trend rather than a single, standardized system, so you may see slightly different interpretations depending on which specific video or creator you're referencing.
How the trend is actually used socially
The trend generally works like this: someone gives a specific can tab to a friend or love interest as a small, low-stakes, often flirty or affectionate gesture, letting the tab's shape "decide" what happens next (a hug, for instance). It's meant to be playful and light-hearted, similar in spirit to other simple, low-commitment romantic or friendly gestures that have circulated as social media trends (comparable to trends involving nail polish colors or other small symbolic objects used to signal interest or affection in a low-pressure, game-like way).
The DIY and craft use of can tabs
Separate from the romantic/social trend, can tabs have a genuine, longer-standing use in DIY craft culture: making jewelry (bracelets, sometimes more elaborate chainmail-style pieces), recycled fashion projects, and charity collection drives (some organizations have historically collected can tabs specifically for recycling value to support causes). This craft use predates the TikTok romantic trend and continues independently of it, showing up in tutorial videos, upcycling content, and resale/handmade product descriptions.
Why context determines which meaning applies
If you encounter "can tab" in conversation or online, the surrounding context tells you which meaning is intended:
- A craft or upcycling post → almost certainly the literal object, used as a material
- A TikTok video with romantic or "crush" framing → likely referencing the symbolic trend
- General, casual conversation about drinks or recycling → the plain, literal meaning
Frequently Asked Questions
Is the TikTok can tab trend an official, standardized system?
No, it's an informal, user-generated social media trend without one single official standard; specific meanings assigned to specific shapes can vary somewhat between different creators and posts.
Do people actually collect or save can tabs for a specific charitable purpose?
Yes, some charitable organizations and school fundraising drives have historically collected can tabs (rather than whole cans) specifically for their scrap aluminum recycling value, a genuine, if smaller-scale, practice separate from the social media trend.
Is this trend something adults participate in too, or mainly younger users?
While it originated and remains most visible among younger social media users (largely on TikTok), the playful, low-stakes nature of the trend means people across a range of ages have engaged with or referenced it, particularly as a lighthearted, nostalgic callback for people who remember earlier, similar trends from their own youth.
What's the actual name for the part that opens a can?
Technically, it's often called a "pull-tab" or "stay-tab" (since modern cans use a tab design that stays attached rather than fully detaching, an intentional design change from decades ago specifically to reduce litter and injury risk from loose, detached tabs).
Why simple, low-stakes trends like this spread so easily on social platforms
Trends built around a small, everyday, physical object, like a soda can tab, tend to spread widely precisely because the barrier to participation is extremely low: almost everyone has access to a soda can, no special purchase, app, or preparation required. This is a recurring pattern in internet culture: simple, tangible, easily-replicated actions (assigning meaning to nail polish colors, hair ties, specific everyday gestures) tend to achieve wider, faster spread than trends requiring more effort, cost, or specialized materials, since anyone scrolling past the content can immediately try it themselves with something they likely already have on hand.
The history of can tab design, briefly, since it's relevant to understanding the object itself
Modern beverage cans use a "stay-tab" design, where the tab remains attached to the can after opening, a design that became standard specifically to address safety and litter problems. Earlier can designs (common through the 1960s and 1970s) used fully detachable pull-tabs that separated completely from the can, which created two documented problems: loose tabs became a common source of cuts and, more seriously, choking or ingestion hazards, and detached tabs contributed meaningfully to litter, since people often discarded them separately from the can itself. The stay-tab redesign addressed both problems simultaneously, and understanding this history helps explain why can tabs today have the specific attached, lever-style design that then, decades later, became available for repurposing into the craft and social media trends discussed above.
Why craft communities specifically favor can tabs as a material
Beyond simple availability and cost (essentially free, since they're a byproduct of something people are already consuming), can tabs offer specific practical advantages for jewelry-making and textile-adjacent crafts: they're lightweight, have a built-in hole structure useful for threading or linking pieces together, and their aluminum material is easy to work with using basic tools, no specialized equipment needed to incorporate them into a bracelet, keychain, or larger woven piece. This practical suitability, combined with the appealing "upcycling" or sustainability angle of repurposing something that would otherwise be discarded, has made can tabs a genuinely persistent, recurring material in DIY and recycled-craft communities well before and independent of any specific viral social media trend.
