The phrase plays on casual internet slang where ight shortens alright and imma shortens I am going to, reshaped by meme spelling into fuhh wit u. Clips like this spread through short-form edits and soundboards because the elongated vowel can stand alone as a reaction. It sits alongside similar drawn-out voice memes such as Fahhh, where the humour comes from delivery rather than dialogue. Its short length and recognisable cadence helped it circulate in gaming, prank, and reaction videos, where creators reuse familiar sounds to signal mischief instantly without explaining the joke to viewers.
