Goke=Good + Joke = Good joke
Is a sarcastic term used as an adjective to describe a joke that isn't
funny ( see. Shoke for a funny joke). A goker is a person who regularly tells non funny jokes.
The pre-fix of G can be commonly used in front of everday words to describe things which are
bad. ie. Goor = Good Door which is actually a
bad door which is poorly made.
