The phrase comes from everyday French youth slang, where wesh works as a casual greeting or reaction and calling someone G marks them as a genuine, respected person. Short clips built around the line have circulated in French-language TikTok edits, reaction videos and meme compilations, where the slang itself does most of the work. Because it is short, instantly recognisable to French-speaking viewers and easy to drop over almost any impressive moment, it keeps showing up in new edits long after the original clips fade, especially among creators who mix street slang with humour and hype.
