When you really liked someone, but they turn out to be a complete ***hole, so you dump your respect for them by throwing it out of a window at them. Along with some complimentary rocks and an old shoe for bad luck.
"Oh girl, I am so crush dumping that b*tch-***hole-d*chebag. He lied about everything and he didn't even apologize. Lemme just run him over with a truck."
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.
