The exact origin of the tughghhgghh sound is not documented, and it appears online as a user-uploaded clip rather than a line from a known film, show or song. Its name is simply a phonetic spelling of the throaty noise itself, the kind of sound people type when they cannot describe a growl or grunt in words. Because it is strange and instantly recognisable as a reaction, creators have picked it up for meme edits, reaction videos and short-form clips, where an odd vocal noise can carry a joke without any dialogue.
