The person(s) in a group of friends or co-workers that all too often will end a funny strand of joke so terribly that it will seem intentional. The "killer" should be ridiculed for a large quantity of time after the kill, and to be presented with this definition and a right-handed slap of the face.
Dan "man shes so fat they're gonna have to open both doors to get her in."
Killer "ya and she prolly has to tighten her belt too! lol!"
EVERYBODY "wow wtf was that...stupid joke killer, go kill yourself"
