n. Describes a person's (or group of persons) inability to hit the target with their guns, even at close range. Reference from the Star Wars movies, where the Storm Troopers tend to have trouble even grazing the rebels with their laser blasters when chasing them down.
A Russian Storm Trooper can also be known as a "ZR" aka Zeke, and has absolutely nothing to do with russia, russians, or anything related to russia. A russian storm trooper can be found in it's natural habitat asking around for food (commonly tacos) in a freshman class. Since the russian storm trooper is nocturnal, the russian storm trooper will naturally ask for food then fall asleep for the remainder of the class.
Russian Storm Trooper: Hey dude, can I have some of your tacos?
Other Person: Sorry man, I didn't buy extra's.
Russian Storm Trooper: Please man, I didn't eat breakfast yet and I'm starving!
Other Person: Dude, don't be such a Russian Storm Trooper.
The person at the back of an anal sexual encounter. While the term is most often used as a derogatory reference to homosexual men, it can equally well be applied to lucky bastard straight guys who find women who will let them fuck them in the ass.
