grand slam

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."

Hey I hit a Grand Slam with this chick and some help from my best buds last night.

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.
