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.

Grandama Canal

This term is used to describe when one is having unlubricated sexual intercourse with their grandmother, but the hard penis is too sturdy for the grandmother’s saggy and dry vagina to handle, thus ripping the walls off of the vagina like paper and the blood pools and fills up the vagina, imitating the water in the Panama Canal.

Person #1: Hey bud, how was your grandmother yesterday?

Person #2: Not too good, I created a Grandama Canal and she had to go the the gynecologist.
