look up any word, like hipster:
Whiff-A-Shit occurs when you are suddenly over taken by a pungent but, not over-bearing smell of shit or dirty ass.
1. When I bent down to pick the box up off the floor I got a Whiff-A-Shit from the old mans ass.

2. I sat down in the old mans easy chair and got a Whiff-A-Shit.
