A sexual act derived from the bowling term that describes the event that a player misses only the back corner pins on his first roll of a frame.
While fingering a girl after doggy style (using two fingers), insert your thumb into her anus which is similar to the way you would grab a bowling ball with finger holes. Then proceed to "roll her" into the headboard/wall.
The name comes from the fact that it is almost impossible to get a spare after a 7-10 split, and it will likely be impossible for you to have any future relations with this girl if you pull it off.
Guy1: I wanna break up her with but I hate the damn break up talk.
Guy 2: Dude, just give her the 7-10 split, she'll never call you again.
