A Dirty Courtney is the act of when your gf/bf spontaneously taking advantage of you, completely ravishing your entire body with body twitching full body orgamisms, fulfilling your every dirty kinky fantasy over and over again.
the dirty straw is when two people are making out, and one of them burps silently but does not stop kissing, and the result is that the one person blows their burp breath into the other person's mouth. this is called giving someone the "dirty straw".
"I was really turned on by Mike's kissing, until he had the nerve to try to get away with giving me the dirty straw. It was disgusting."
Meeting in the pub on a thurs drinking yourself stupid turning up for work on a fri stinking of booze unable to speak man that was a good Dirty Thursday
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!
