With no clear credited source, this clip circulates purely as a shareable reaction sound on soundboards and in short video edits. The phrase combines two familiar internet attitudes, instant confusion at something bizarre and a blunt refusal to care about it, which makes it easy to reuse across many contexts. Clips like this spread because the line is self explanatory even without context, so creators can drop it onto gameplay fails, weird animals, strange objects or awkward social moments and the joke reads immediately for new viewers.
About this sound
A confused voice clip saying what the crap is that, I don't care, used as a funny reaction sound effect for weird, gross or unbelievable moments online.
This is a short spoken reaction where a voice spots something strange, blurts out what the crap is that, then immediately shuts it down with a flat I don't care. The delivery jumps from startled confusion to total indifference in seconds, which is what makes it funny. The first half sounds genuinely baffled, the second half sounds bored and dismissive, and that swing lands like a punchline. It works because viewers recognise the moment of seeing something cursed or nonsensical and deciding not to waste any more energy on it.
