It is said when a meal look so terribile and smells so disgusting that it evokes the image of a vaginal fart (aka queef).
"Jesus buttfuckin Christ, what's this terrible smell? It smells like truffle butter mixed with dogshit"
"My gf spent the whole morning making this meal for me before leaving for work, but never told her she's fucking terrible at cooking. Would you do me a favor and eat this for me?"
"You sick mofo. You know I can't say no to my best friend. Well, bon app-a-queef, I guess."
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
