What is Kahn!?
1.
The name of an vile enemy in the original Star Trek series. You usually use it after getting like really mad and blame someone. This is what William Shatner did on the T.V. show Family Guy. (And if you think this definition sucks, make a better one!)
Somebody stole my car! KAHN!
2.
Another definition? Bellowing scream of rage also used by george in a Seinfeld. For that matter
KAHN! pronounced as, "Kahhhhhhnnnnnn.....!" in a shattering call rising from the depths of despair.
