look up any word, like cunt:
A circumsized penis that is usually pretty short to begin with, when in an extremely flaccid state (i.e. when thinking of Babs Streisand naked) the head recedes into its own wrinkled shaft producing a button dick effect.
Overheard in a locker room "Hey man what you got there? An Innie Dick?"
