OBCO
A person who can't stop doing the same stupid thing again and again, especially in online games. Some take pills to get better, others just get yelled at by their friends.
''Why did you kill that mob 20 times? You're making me mad!''
''I'm not done with this dungeon yet! You can't just leave!''
''You said you'd be here in 5 minutes! It's been 30!''
