Grand Slam 

A term in baseball when there is a runner on 1st, 2nd and 3rd, base; then the player at bat hits a home run and four runs are scored. Somewhat rare.

Do I really need an example for this? Grand Slam

Grand Slam 

Series of the following sexual positions performed in succession while maintaining continuous penetration: missionary then flipping to cowgirl then spinning around to reverse cowgirl and finishing with doggie style.

My boyfriend and I were so inspired by our team's gland slam that we celebrated with our own grand slam!

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.
