Begone thot grew out of internet slang, pairing the old-fashioned dismissal begone with thot, a slang term used online to mock someone seen as attention-seeking. The phrase spread through short meme videos, reaction clips and social posts, where it became shorthand for telling someone to leave a conversation in a funny, exaggerated way. Because it is only two words long, it fits easily into edits, streams and comments, and it has stayed popular as a quick, recognisable rejection line rather than fading with a single viral video.
