Billy is a man-child, who is a muscular athletic human. Who posses many talents. He is easily amused by childish things oftenly confused with 'ADD'. He is a passionate lover and has a monster cock. Women crave his attention, while men envy him. Gay men flock to him and he disrepectfully declines with his man strength. Teachers chat about him behind his back and act as if it never occurs
That guy is a billy, if there ever was one.
