Score Whore

A player (typically very obnoxious) that is obsessed with beating your high scores. They will follow you on leaderboards for the sole purpose of getting a score higher than yours so they can brag about it...causing you to either take time out of your day to go "fix it", or let them gloat forever.

Player 1: Hahahaha. Look! I beat your high scores again on 3 maps today. Tee hee hee. I can't believe it!! Blah blah high score blah blah blah scores blah blah highest score blah blah blah score.
Player 2: Ugh. I'll have to go fix it. Thanks, you score whore.
