When you are on a trampoline and someone does that thing where they land just before you do and by some mysterious act of physics they launch you like five thousand feet in the air and you're like,"Shit nigga you just gave me mega chunder!"

The Diarrhea smelling nastiness that is a container of food left in the fridge that is there for 2 months, that becomes so nasty, and fetid that you almost projectile vomit all over your self and your surroundings when you lift the lid and break the seal of the mold laden nastiness contained within.
