poltergeisting

When someone tries to ghost you, but because you have a lot of mutual friends or share a common hangout, you keep running into them and they act like they don't know you. They become more of a negative presence that won't leave than a ghost.

the poltergeist is a fairly common sexual act where a man is giving coital intercourse to a woman from behind. when things get really heavy, the man pulls his penis out and has his buddy, who may be named Karl or a different name, sneak his penis into the woman without her noticing the difference. the first man then sneaks outside and waves casually to the woman, through the window, very much to her surprise.

A kind of ghost or aparition that manifests itself by physical activity (moving things, slamming doors/windows, etc.)

"Geist" = German for "ghost"

a male that kills himself in order to come back to the human world as a freaky ghost and haunt the house of a hot babe in the hopes of scaring her out of her clothes

When a man gives it to his female partner from behind, then pretends to fall out and switches with his best bud. He then runs to a window and waves at his girl while she takes it from his bud.
