A Grandslam is the upgrade of a Strikeout. Whereas a Strikeout is consumed in the order of marijuana, liquor, and beer, a Grandslam is performed by conusuming a line of Cocaine to leadoff the order. So it goes line of Cocaine, Bong Rip, Shot, Beer Chug, Release smoke. Grandslam.
Jack took a shotgun last night and was a badass until Ryan outdid him by pulling out a line and introducing us to the epic grandslam.

When you have sex with 3 different people in 3 consecutive nights, or 3 different people in one night. It's called a grandslam because you made it to home with 3 people.
Dude, I've got a Grandslam lined up for this weekend! Christy on Fri, Susie on Sat, and Becky on Sun!

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."
