Online, gug gug gug works as a written and spoken shorthand for heavy gulping, so editors label chugging clips with the phrase itself rather than a character or show name. The sound spread through short meme edits, reaction videos and soundboards where a long, obvious drinking noise can replace dialogue entirely. It stays useful because viewers understand it instantly even on mute as captions, and because the repetition lets creators stretch or trim the joke to match drinks of very different sizes.
