Grand Slam

When you fuck six girls at once by sticking your dick in one girls, your tongue in another, and your hands and feet in the pussy of the four remaining girls. Note: there will be a lot of moaning and it will look like you have girls growing off of your limbs.

I just Grand Slammed the six hottest girls is school last night!

Granny Grand slam

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.

My friends and I took some granny grand slams last night, we got peeled back!
