A person in a first person shooter who jumps in order to gain an advantage over an enemy. This maneuver may be executed while turning a corner to surprise their foe around said corner, or in open conflict. When killed by a jumper nazi, one feels the need to rant about their death, insulting the enemy, and try to convince themselves that they would have killed that bastard had they not jumped.
SMSchoirboy: Damn it, that jump nazi just got me... damn n00b.
TSwift_is_a_babe: I'm such a n00b.
