3.
When a group of horny highschool boys (from an all boys school in Nashville, Tennessee) call up about 50 girls who all say no except 5 hoes, usually in the grade below, to agree to sneak over and get "wasted" in the rich boy's pool house.
"Dude, I think I got an STD from that late night tip last night with Mary."

or

(ON THE PHONE): "hey, we're gonna come get you on the late night tip at your house and take you back to john's, fuck you, then you can get a cab ride home"
