Roof Ninja 

1. In modern First Person Shooters, these are the players that find the highest spot in the map or some inconspicuous place on a ledge until they time it just right to attack.

Then, they proceed to camp in that spot again until the next victim. They rarely leave that place because they have deemed it the most advantageous spot to camp, hardest to reach to counter-attack, etc.

(often a glitched spot in CoD or a place worthy of expert UT trial runners)

Any game of Call of Duty, BF2, Unreal Tournament.

"Zomg will someone kill that roof ninja. He is a no talent ass clown who sucks at camping."
