“Oh yeah that’s pretty cool” has been my go-to, whether drunk, sober or high.

Craaaaaaaayyyyyyyyy

“Wtf man” in an empathic tone if they appear to be saying something sad or enraging

Very true, but it’s also true when I’m sober af.

… oh, you’re still talking? “hahaaa, damn that’s crazy/wild/weird/interesting/cool”
