1. A phrase added onto a sentence or story when the content incites excitement or emotion too extreme to be accurately conveyed by verbal description.
Not to be confused with You don't even know, which suggests that the emotion or sensation cannot be described not because it is too powerful but because it is unique to the person experiencing it.
"My mom sent me a birthday text, and it was SOOOOOO cute, like, your daddy don't even know!"
Something to tell a hooker in the throes of passion while slapping her ass, or your missus which would either result in increasingly intense fornication or your status changing to single.
#The more the daddy issues, the more useful the phrase.
'Who's your daddy?' said Dr. Long as he slapped Nursie on the buttocks.
'You are' says Nursie (being a pornstar with issues and all)
'Who's your daddy?' says Fred.
'He died last month asshole' Sarah says as she slams the door on her way out.
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??"
