1. When one person on the edge of your social group kills every joke as it is being told.
2. When your watching an episode of a TV and your friend finishes all the lines before they are said.
1. Jared: So i heard a woman had a tree fall on her and i was like what was a tree doi...

Nick: In the kitchen

Jared: You suck.

Everyone: Joke Homicide
2. Peter Griffin: Your a good boy chris for following the law...

Nick: But you meg your goin to jail!

Jared: You still suck.

(Repeats)

Jared: Joke Homicide!

3. Alex: Yo Nick is killing every joke today...

Nick R.: Yeah i know hes totally committing Joke Homicide!
