The act of taking a dump in the tank of a toilet.
Step 1: Quietly sneak into the bathroom unseen
Step 2: Carefully remove the top of the tank. Note the porcelain tank top is very delicate and will shatter if dropped
Step 3: Climb on the toilet, drop pants and sit on the tank. Imagine you are a bird sat uptop your nest, sit very softly or else the tank may break and the operation will be compromised
Step 4: Take a monster shit. I'm talkin like a goddamn mudslide out your asshole
Step 5: Whipe and throw the tp in the tank too for good measure and put the top back on
Step 6: Return to the party and act like nothing ever happened, if you leave right away you will draw suspicion to yourself
Step 7: Enjoy the host's reaction when they see that Mount Vesuvius just exploded in their toilet tank
