OBCO

Derogatory slang for obsessive compulsive personalities especially when they are exhibited in multi player online game communities. Many obcos go on to lead semi normal lives with the help of medication and ass kickings while others become trapped in repetitive pointless behaviors.
What an OBCO , you see how he keeps checking and reloading his noob toob?
