고수 Gosu
Wikipedia’s Defenition
In Korean, gosu (lit. a high hand) is used to refer a person with great skill, usually in martial arts or in baduk. Currently on the internet, gosu often refers to a good player or item in computer games, such as Warcraft III: The Frozen Throne, Diablo II, Lineage, Lineage II: The Chaotic Chronicles and StarCraft. On the other hand, one with no skill can be labeled as a "Newbie"; which is considered to be opposite of "Gosu" in the internet gaming world.
The word comes from the Mandarin Chinese term gao shou (also 高手
, which also literally means high hand. A gao shou is someone with a large amount of skill.
An urban legend holds that gosu originated as an acronym for "God Of Starcraft Universe"; however, this is actually a backronym, as the term has long been applied to players of other games predating Starcraft and martial arts experts.
Gosu can be shortened to the adjective form "gos" in the gaming world, often referring to a move or combo. "That headshot was hella gos."
There are also commonly used Korean words for "a quite good player" (jungsu) and "a mediocre player" (hasu) and "a bad player" (chobo).
Different forms: Revised Romanization: Gosu, Hangul: 고수, Hanja: 高手, McCune-Reischauer: Kosu
