An attack often seen in television shows involving giant super robots (or robots in general), where the robot's fist or lower arm shoots out as a projectile weapon.
Did you see that robot improvise a rocketpunch by ripping its own arm off and throwing it?
It's like a donkey punch, but instead of injaculating in her anus after hitting her in the back of the head, you stick your arm in her anus more than 4 times.
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.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
