Slang. Also written cap, capping, no 🧢.
Comes from African American Vernacular English, where "capping" has meant exaggerating or boasting since at least the mid-twentieth century. It reached mainstream use through Atlanta hip-hop in the 2010s, and the 🧢 emoji became a shorthand for calling out a lie.
Three related forms do different jobs. "No cap" appended to a statement asserts sincerity. "Cap" alone, or the cap emoji, is a reply accusing someone of lying. "Capping" is the ongoing act. The word carries a specific cultural origin, which is the thing brands most often overlook when adopting it.
Reads as authentic from an individual creator and as costume from a corporate account. If your brand voice is not already casual and young, this is one to understand rather than use.
It means "no lie" — an assertion that what was just said is genuine and not exaggerated. It functions roughly the way "honestly" or "I swear" does.
A lie. Replying "cap" or sending the 🧢 emoji is calling out something as untrue, usually as an exaggeration rather than a serious accusation of dishonesty.
It originates in African American Vernacular English, where "capping" has long meant boasting or exaggerating, and entered wider use through hip-hop. That origin is worth knowing before using it commercially.
