The ability to be constantly bugging someone, and no matter how hard you try to get away from the mapper, it still seems to be grabbing onto you.

Also, a mapper is sometimes a Party Pooper. It'll fight, and contradict you in almost every subject until the point where you just give up.
MAP ATTACK
Friend: "Oh man, I am so sore from work."
Mapper: "Oh yeah, try 3 hours of Rugby practice!"

Friend: "Aww, I have to go to work for ten hours!"
Mapper: "Oh yeah, I worked at the bigstop for 13 hours straight! I didn't even get to take a nap!"
