when you are at a social gathering like a party or an orgy and one person has a deadly fart that no one hears and he/she gets up and moves his/her hands in a sweeping motion like sweeping the floor and then everyone gives a good wiff of the nice stench
what are you doing??

Get the crop sweep mug.
When you fart while having sex and grab a handful of the fart gas and throw It in the persons face
I just love it when a guy keeps crop sweeping me during a jungle pillow
