Jack stick 

Douchebag. Self centered, opportunistic, and untrustworthy. His kindness, charm, and friendships with others are his toolset to maneuver toward his own selfish desires.

That guy who just flew in on his friends jet to the charity event is such a jack stick.

jackstick 

A 23 year old male with beady eyes, baggy jeans, poorly made tattoos and a sleeveless shirt for displaying them. The jackstick is almost always found hanging around near gas stations trying to pick up 13 year old girls getting slushies after soccer practice.

I was getting gas while my daughter went in for a fountain drink. This jackstick tried to talk to her, so she kicked him in the balls just like I taught her.
