This is not a flanker bud, I am a flanker and I do not do this...
Flanker: Someone who finds a route to get behind your team and take them out.
Example: On Afghan, if your entire team is over by A in domination..., I will go all the way around the mountain passing C and the back of the cave to get behind them and take them out.
Camper: Someone who stays in a room/spot the entire game, if they die they go right back to that spot or to another spot doing the same thing.
Example: In Underpass there is a dark spot by B(Domination), a camper will stay there killing your team until he gets killed.
Worst for the team: Flanker
Worst for you: Camper
