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.
