Mouldy ass

when you don't wipe your ass & it forms a layer of mould in your ass crack, which smells & makes other people gag when they walk past.

Oh my god the seat smells, the last person who sat here must have had mouldy ass.

a bag of old and moldy ass

This is a person who drank way too much the night before.

"Man I feel like a bag of old and moldy ass"

Moldy Leftover Ass lint

Usaully you get it when you haven't bathed in a while and it collects in your crack and it suddenly becomes stuck with no way to get it out.

There's some in your crack.......
