Mass party

Huge party typically full of teenagers and early 20 year old guys looking for a quick root. Best to go to these parties fully clothed unless you're looking at getting pregnant or paying child support for the rest of you life. Mass parties generally don't have honourable amounts of food just booze and weed. Best mass parties are hosted in halls and clubs with mean lighting set ups

Chad: " yo Harley did you hear there's a mass party on Saturday?!"

Harley: " yeah I did, ifts going to have all the bass drops and sickest lighting set ups, I heard there's going to be over 300 people!!"

Law of Conservation of Mass

Atoms cannot be created or destroyed. The mass of the reactants entering an equation must equal the mass of the products exiting the equation.
“What goes in, must come out!!”

The law of conservation of mass is a fundamental principle of physics.
