monster dump
a giant shit, a big poop, a humongous dookie, a large BM
"Sorry, I can't talk right now. I gotta go take a monster dump."
Double Monster Dump
The double monster dump, abbreviated DmD, is where you dump so big that your dump comes out of the john and takes another dump on top of your dump.
Yo lil cuh, i just took a dump and then in dumped on top of my dump. It was a Double monster Dump.
Monster Truck Dump
An absolutely enormous shit. A shit so big you can proudly take it home to your parents. Your colon living out its dump truck fantasies.
The day after the buffet, I took this monster truck dump. A serious two foot turd. I felt like a great waste had been lifted from me.
