Comes from a mispronunciation of the words "get good", meaning basically "learn how to do it" "get better" and is commonly used in a majority of online
videogame community in a negative meaning, to mock someone who's having problems with some section of a game. In
Dark Souls community is a commonly used phrase, mostly by elitist shitheads who think they're gods made flesh just
because they can play this game in a certain way.
