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!
a Dirty Damon is when one shits in another mouth and the person with the shit in the mouth try's to gargle it then spread it on the others face while putting their pubes and ass hair on the others face making it seem like they are a dirty Damon they then proceed to suck the other off and then spit the cum on the others face adding to the mix of shit and hair.
guy: hey babe wanna do a Dirty Damon tonight?
girl: whats a dirty Damon
guy: ill show you ;)
girl: OH GOD WHAT ARE YOU DOI-
guy: shhhhh just let it happen
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
