Sexual act derived from the famous game character Kirby. This is when a person is able to put a man's shaft and both balls in the mouth (licking the balls while performing this is a huge plus). Because of this, the person's face becomes rounded and bigger, resembling Kirby.
I don't know how that bitch over there pulled off the Kirby on big dick DJ.
