What is Dirty Damon?
1.
When a couple is engaged in intercourse, then one of the two proceeds to excrete fecal matter onto the others face, and then shaves his(or her) pubic, taint and ass hairs on top of the crap, as to imitate Matt Damon's beard. (distant relative of the abe lincoln)
Oh my Gosh hun, that dirty damon was so thorough that if I saw you on the street with all that crap and pubes on your face, I would have asked you for your autograph!
