Ass fog

A fart so pungent the smell lingers in the air, like a thick fog.

Irwin: Oh my God, what is that foul smell? It's stinging my nostrils.

Bryan: That's my dog, Odin. His air biscuits are pretty intense.

Irwin: Dude, that ass fog is so bad I can practically see it linger in the air. What do you feed that animal?
