Hilarious quote by Arnold Schwarzenegger in Kindergarten Cop. Used excessively in Arnold prank calls which can be quite hilarious. The term who is your daddy which derrives from this usually is an expression of personal superiority to someone else or to emphasize a victory.
Johnny just beat Tom in a videogame.

Johnny: "Who is your Daddy?"

Jim is screwing Sharon and making her scream quite loudly in orgasmic ecstacy

Jim: "Who's your daddy bitch? Who is your daddy??"

Sharon: "You!"
