When you're a Majacula (Magician Dracula), and you're looking for Zirconium, but you really have to bang one out, so you jerk off but then immediately make your cum disappear as it exits your 'wand'. Fapacadabra!
Damn, it's been a long time since I've been sawed in half, if you know what I mean, but I don't want anyone to know I was playing with my cup and balls in here. Guess I'm gonna have to majaculate!
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.
