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.

Association Smell

The smell of something that reminds you of something else or a past experience.

Dude, I shared pancakes with my ex-girlfriend right after we had sex, so now anytime I get that association smell, I get an erection.
