a guy who's amazing at giving women head. A true cunninglinguist. long tongue, skill, not afraid to get wet behind the ears, etc.
Girl 1: "Hey, did you get what you wanted from your man last night?"

A fun guy to be around with. Smart and knows everything. A bit of an egomaniac. William is usually funny at times, but he likes to make lots of "your mom" jokes. Don't try to debate with him, as you'll be disproved very quickly. A perfect match for Grace.

Variants include: Will, Bill.
That person is amazing! He must be William.

An above average grade student, with a varying degree of popularity and social attributes. Often attracts the attention of female women things and plays with them effectively. Occasionally chased after by males but rejects them certainly. William's are not associated with homosexuality. Total stud.
Oh my god! There was the cutest gentleman down the beach.. What a William!
