In the same family as its cousin the 'wet willy,' the Wet William is the act of punching your junk while your significant other is sound asleep, maneuvering your near-ejaculating penis up to their ear, and busting your load.
Oh that? I was bored and you were asleep, so I had no choce but to deliver you a plentiful load of Wet William.
