Grand Slam Dump 

A large shit that involves sweating and strainging so much that a change in wardrobe is necessary. Counting down from 10, start removing all your clothes. When all clothes are removed, release the load of shit from your anus and yell "Grand Slam". Then, if you are Spencer Meyer, continue to masturbate on the spot.

Dude, I just took a grand slam dump. It was awesome. Thats the second one this month!

grand slam it up your ass

Originating from the popular breakfast platter, the Grand Slam, it is the act of a male wrapping his dick in bacon, biscuits, and sausage links, and using egg yolk as lube, then shoving it into someone's ass repeatedly while pouring syrup down their back and screaming "Breakfast is the most important meal of the day!"

Becky, I was going to make breakfast, but when I opened the fridge, I realized I had used all of the breakfast food to grand slam it up your ass last night.
