Erm what the sigma is a brain rot slang like Skibidi or rizz, it comes from a brain rot version of a clip of a reaction YouTuber going “um, what the heck” and later became a big meme
Person 1: Ayo what’s up my rizzler
Person 2: erm what the sigma, where’s my Skibidi slicers?
Person 1: so sigma my Skibidi
Person 2: erm what the sigma, where’s my Skibidi slicers?
