A korean word literally meaning "exceptional" or "superior", in contrast to the hasu "mediocre" and chobo "beginner". Most often used in the games Starcraft and Warcraft to define players such as SlayerS_'BoxeR', PussInBoots, Seijooro, BMI.PhilMiraldo, NhomerS, APM70, SweetSaint, and SK.Insomnia.
He is a gosu Human player, able to micro-manage his footmen and riflemen with a rapid speed.

Night Elf is a versatile race, whose fragility is only handled well within the hands of a gosu player who can avoid the onslaught of piercing and siege on the race's characteristic unarmored units.

A sub-human who sacrifices his or her social and sex life in exchange for ungodly Starcraft or Warcraft abilities. There have been actual cases where many 'gosu' players had starved to death because of playing Starcraft for too long.

Gosu: "Hahahaha! I can make 82973 zerglings before you can even send your SCVs to the minerals! I'm the best! I FEAR NOTHING!"
You: "...except natural light."
