While trying to have sex with a girl anal but your penis is either too large, or the anus is too dry; you wait for her to fart then you shove your penis inside her as it opens up.
Dude, I tried banging her in the ass, but I couldn't so I executed a "Whoopie Cushion."

My farts are extra loud right now, thanks to my whoopie cushion ;)
