When you short a stock, then get up and take a massive dump, only to come back to see that the stock has gone down a lot (dumped)... so you make a lot of monies.
Tom decided to short AAPL, then felt a little queasy from his Chicken Tikka Masala lunch, so he took a massive poo. AAPL's stock price decided to take a dump simultaneously. Now that is what I call a good ol fashioned Dump and Dump

As in "take a dump, then dump it on your mom"

A pro strat to avoid that situation where you go take a dump, and when you come out people look at you like "I know you just pooped". Take a dump in your pants and give it to your mom to wash, and when shes like "WTF? POOP?!??!?!" Just be like "Woah! How'd that get there?" and walk away. Problem. Solved.
Dude, the other day I just got fed up with people giving me that "I know you just pooped" look, so I dumped in my pants, then dumped it on my mom. The dump and dump

A common sign that means, contrary to popular belief, that it is illegal to drop off trash in the specified location. This trash may or may not include human fecal matter. This sign will never cease to amuse high school kids.
Joey: "Hey, guess what guys? Check it out! I just put up a "No Dumping" sign above the shitter in the boys' room!"
Marty: "HAHAHA!!! All right! Awesome joke! You da man!"
Kenny: "Yeah dude, that's totally rad!"
