Ben : Did you hear that Logan cream pied all of alec’s ex’s holes twice last night?
Connor : Oh my god! He really hit a double grand slam?
Ben : Yeah, Alec is going to be so pissed.

Get the double grand slammug. When four or more of your friends hook up with the same girl at different times. Can only be completed if each person goes all the way (i.e. hitting a home run).

Get the Rhode Island Grand Slammug. Take a Dab, take a shot of liquor, take a bong rip of weed, chug a beer, and exhale. All in one breathe makes the "granny grand slam". First performed by a youtube "grandma". Taking the "strikeout" to the next level.
