dump pumpkin 

a prank involving using a pumpkin as a container for human fecal material is left to decompose for several days yielding a vat of rancid shit, festering and ready to be cast upon the porch, driveway, or vehicle of an unsuspecting often deserving individual or family; this prank is commonly used between the dates of October 25th and November 6th (when pumpkins are readily available) ;often associated with hatred of a specific individual, race, culture, or political affiliation

Stu: Hey what do you want to do tonight?

Steven: I just remembered we have several partially decomposed totally rancid dump pumpkins left from Halloween.

Brock: Lets go throw those on Laurens doorstep!

John: Yeah, that way shit and decomposed pumpkin meat will explode on her personal property and cause the odor to permeate in to the brick and/or concrete, leaving her porch smelling of festering veggie shit.

wicked dump

A time in which a person is not able to poop for an extended amount of time. After hours and hours of buildup, the person finally releases a Krakatoa in the toilet.

That Edward Postma destroyed my toilet with a wicked dump.

sonic dump 

When you gotta take a poo so bad but you aren't anywhere near a legitamate place to go so you hold it in for an hour until you finally get to a toilet and by this time you can hardly wait to get your pants down when it just blows out your ass, and everyone else around you knows exactly what you just did.

Man, they had to repair that toilet in the public 'room after I took that sonic dump last week. I still can't look at Jesse straight after he took one a few months back while I was in with him.
