A guy with an above average sized dick, who thinks his dick is so good that he can fuck any woman, including your best friend or your sister. His dick preempts him from any human ethics, whatsoever.
That guy thinks he's Mr. Dick! He was flirting with my best friend right in front of me.
Guy in the gym locker room who walks around with the towel around his neck and his dick is hanging loose.
Hey look Mr. Dick is brushing his teeth with his shlong resting on the counter.
