A 9 mark round is when you have sex with a bitch for 3min in the mouth, 3min in the puss and 3min in the ass. 3+3+3=9(Like in darts when you trow 3 darts in one round and hit 3 tripples)
"Hey Sammy did you fuck that slut from the bar the other night."
Sammy - " Hell yea, that was a dirty bitch. I gave her a great 9 mark round after I was done with the 3rd minute in her ass I pulled out and blew it directly in her eye. She loved it."
