yap
To talk at excessive length, especially in an aimless, repetitive, annoying, or low-substance way.

What it actually means
To yap is to keep talking, often longer than the listener thinks the subject deserves or without reaching a clear point. It can dismiss someone's speech as annoying or meaningless, as in "What is he yapping about?", but modern users also reclaim it affectionately to describe enthusiastic, comfortable conversation. Related forms such as "yapper" and "yap session" can therefore function as either insults or playful self-descriptions.
See the quick definition in the yap dictionary entry.
Where it came from
Yap is not a newly invented TikTok word. Dictionaries trace it to an imitative English word for the sharp bark or yelp of a small dog: Merriam-Webster records use from 1596, while the Online Etymology Dictionary dates the dog-sound sense to around 1600 and the human meaning "to talk idle chatter" to 1886. Forms such as "yappin'" also appeared in twentieth-century speech and rap, including 1990s and 2000s recordings, before TikTok users revived and remixed the vocabulary. Know Your Meme documents memetic TikTok use by January 2022 and a viral July 2022 cat video captioned "Straight to yapping," followed by broad spread during 2023; no single modern coiner has been verified.

Where it's popular
The current slang is especially common across English-language TikTok, X, Twitch, YouTube, Instagram, gaming and streamer fandoms, reaction-video communities, and Gen Z and Gen Alpha meme culture. Rap lyrics and Black American speech helped preserve familiar forms such as "yappin'" before the TikTok revival, but the underlying English word and its talkative meaning are much older and are not exclusive to one regional or ethnic community.
The modern trend is better described as a platform-based revival than as slang invented in one country. TikTok popularized new formats and a more playful identity around being a "yapper," rather than creating the base word.

Common mix-ups
Yap was not coined by TikTok, Gen Z, a streamer, or a single rapper; its human-talk sense predates social media by well over a century. It also does not always mean that the speaker is literally saying nothing of value: people often use it hyperbolically for any long explanation, and some proudly call themselves yappers. The unrelated noun "Yap" can also refer to the Pacific island and state in the Federated States of Micronesia.
