The phrase combines gyatt, a clipped form of an exclamation popularised in livestream chats, with damm for extra emphasis, and it spread mainly through short form video and soundboards.

Ramal ig appears to be the uploader tag attached to this version rather than a character or show, which is common for reposted meme audio that circulates under many slightly different names.
