Ass smells like Foldgers 

1)If you are partaking in a coffee enema and you leave said product in too long, your ass will smell like coffee grounds.

2) Over hearing someone say "crass and vulgar" and thinking they said "Ass smells like foldgers".

Kate: Mmmmm, did someone make same coffee?
Arturro: No, Reese is suffering from a botched coffee enema.
Kate: Well, his ass smells like foldgers.
Arturro: I can make some coffee if you want?
Kate: Umm no!

Reese: Oooo! I want some!

Smells like the inside of an ass hole 

The worse smell imaginable because in an ass hole there is a lot of shit and fart concentrated and confined to a very small place.

What is that smell? It smells like the inside of an ass hole.
