When trapped in an office with a terrible case of the farts, one gets up and does a couple of laps around the office perimeter, slowly and quietly squeezing off a continuous ass rip so as to allude to merely stretching your legs while in reality you are letting off some sever bung hole pressure.
When a guy is analing his girlfriend and she farts either on him or on his dick and the smell is unbearable, kind of like curry or any other Malaysian/Indian food.
Guy 1: Bro last night I assfucked my girl and she farted on my dick right before I stuck it in! It smelled like fucking shit!
Guy 2: Haha! You just got Malaysian Crop Dusted.(Another form of Malaysian Crop Duster)
