ass grease 

The lingering stench left behind, after an individual doesn't shower for five days (or more), eats a lot of mexican food, and drinks excessively. Not even half a bottle of fabric refresher/air sanitizer will eliminate this stench.

I dare you to go in Lesley's room because it smells like ass grease. Good luck because you will most likely dry heave.
