Inadvertantly getting one's pubes stuffed into one's condom prior to sex. After sex, the condom is removed to reveal a sweaty mess of matted pubes also known as "hat hair."
I had to put the condom on so fast I didn't bother moving my pubes out of the way. After I blew it, I had a ratty nest of hat hair that was sore for three days.
Hairy Hat Man- is also the character from alphabet land who resembles the letter H, a very hairy character who has a beard, a piece of straw hanging out of his mouth and a farmers hat.
