A abbreviation of "Chinese Gap" used by the famous streamer "loltyler1" to insult chinese players in his league of legends
game. It is a way of flaming the chinks without being punished in-
game. You use it when a chinese person starts spattering chinese that nobody understands(because its not the chinese server), and you reply with a simple statement "cn gap".
It is a sure
fire way of making a chinese person
mad and start typing for the entire game in chinese.
