What does PU stand for?
as in PU that stinks
pretty ugly, like in that old moldy stuff in my fridge smells pretty ugly!shoot i don't know, i tried.
Pick up the smell and take it elsewhere.
It's what people say when something smells bad.
I don't think PU actually stands for anything, i think it's just a shorter way to write peeyew(sp?) which is actually an onomatopoeia for what you would say if you smelled something disgusting, if that makes any sense.
