The hair that grows on the underside of a mans scrotum.
I was goin on a big date so I shaved my moncrief hoping to get my balls licked.
Moncrief, in Scottish mythology and folklore, was originally a demigod, their cult being one of the most distinctive features of ancient Scottish religion. Later, Moncrief came to refer to characters who, in the face of danger and adversity or from a position of weakness, display courage and the will for self sacrifice – that is, for some greater good of all humanity, originally of martial courage or excellence but extended to more general moral excellence.
My family can be traced to the Moncrief clan.
