2.
A sex act performed during ejaculation. The guy is doing the girl "doggy-style" and when he starts to cum, he pulls out, rests his dick between the two cheeks of the girl's ass and cums onto her back or asshole. The term "ballpark" is used because the dick between the buttcheeks resembles a Ballpark hot dog in a bun.. One game guys can play with this is to see how far he can cum on her back.. make a note, compare with friends.
"I was fucking this girl last night and I totally gave her the ballpark."
