A Sexual position. The girl in said position, must be in an arched position, usually rear sticking in the air, to symbolize the St. Louis Arch. To symbolize the grand slam, (Busch Stadium) she must have someone 1; Kissing her 2; feeling her breasts 3; fingering her (For a man on first, second, and third) and someone doing her from behind for a batter. When the "batter" is about to cum, you spin her around, and hit her on the cheek, to make a popping sound, for the "Home Run Hit". To be truly authentic she should not be shaved, for Bush/Busch Stadium.
Guy 1: Hey did you hear Victoria was the first girl to hit an STL Grand Slam?
Guy 2: No, i didn't know there were women in the MLB yet.
Guy 1: There aren't *winks* **Explains**

A large shit that involves sweating and strainging so much that a change in wardrobe is necessary. Counting down from 10, start removing all your clothes. When all clothes are removed, release the load of shit from your anus and yell "Grand Slam". Then, if you are Spencer Meyer, continue to masturbate on the spot.

after a nice breakfast you ask your partner for reverse titty fuck (so your ass is above her face) as you are in the process ask for her to lick your butt hole, if she complies shit in her mouth.
