Gyatt became widely used online as exaggerated slang for reacting to an attractive person, while tjockis is a Swedish word playfully used for someone chubby, and together the pairing sounds deliberately mismatched and absurd. That contrast helped the phrase circulate on meme soundboards and short-form video, where short slang clips are reused as instant reactions. It sits alongside other brainrot phrases and rizz-related jokes, gaining most of its humour from recognition rather than context, so audiences who know the slang understand the intended reaction immediately without needing the original clip or any longer explanation.
