pebble dump 

When it feels like you have to take a mammoth dump, you sit on the can and push until you feel your eye balls popping out of their sockets. Just as the tip of the mountain reaches the nether region of your sphinctorial muscle, it shatters into small pieces, or pebbles...Hence the pebble dump. This particular dump tends to be very mind boggling, playing tricks on the human brain. Just when you get the feeling of having serious shit envy, your dreams are shattered and you are left with nothing but rocky road.

" Holy Crap! Those wings were pretty potent...It feels like I'm about to give birth to one of Bob ross's mountain scenes. Forget it!! It was just a pebble dump. I really need to start thinking about hydration. "

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!
