Tad: dude i think Chad hit a fucking grand slam!
Brad: should we take him to the hospital?
Tad: nahhh, let him enjoy it, it might have just been a home run
RIP Chad

Okay for this you need 4 gentlemen and a chick. A party may be a good place for this. The first three gentlemen need to make out with the chick. They each get to "first base." The bases are loaded as the "runners" advance. Finally the fourth gentleman approaches the chick and proceeds to have sexual intercourse with her. Once he "gets all around the bases" by this act he has "hit a grand slam home run." Or simply a "grand slam." The remaining gentlemen burst into the room and many hi-fives are exchanged while they all yell, "Grand Slam."

a common sex act in the colorado and rocky mountain area in which one sexual partner purchases a grand slam from Denny's restaurant, places the entire meal in his or her partner's ass, and eats the entire thing seasoned as preferred...hot sauce is commonly recommended
I was hitchhiking with a trucker, when we became really hungry. As we passed by Denny's, we decided the best way to fix our qualms would be to share a grand slam.

A foursome. Where as 'hitting a home run' means scoring with one chick, a grand slam means four runs so four chicks.

To awake one fine morn, and verily discover one's matress resembling a ordinance survey map with a rather warm chocolate log spread all over it as well as spew on your face and pillow.
"I do not think she will want to see me again after I came home totally ringbolted and grand slammed the bed, although your mum is a bit of a dirty slapper."

when you are heaving sex with a chick, take out a baseball bat and shove it up into her anal cavity, then pull it back out and hit the chick in the face with it.

As with the other baseball references to the bases (first base, second base, and so on) the grand slam refers to having anal sex. Since it is one up from a home run (just vaginal sex), and doesn't usually happen quite as often.
