The sex act of first anal with a girl, getting head from the female, then nutting into her mouth and then French kissing, getting shit and cum into each others mouths then at the end spit it into a cup for the next time you do a Dirty T, eventually filling up the cup.
Man 1: “Me and my girlfriend did a Dirty T yesterday, it was great!”
Man 2: “I told you it would be good.”
