When the fart doesn't extend outside of the underwear, and when underwear is took off, there is a smell, the smell of the assfog.
Person 1: I just farted, smell this!
*Takes off underwear*
Person 2: Get that assfog smell outa here!

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?
