It is when a party is held at a vacation home and the building and facilities are destroyed. There is a risk that a large number of people will leave the house after a party, leaving behind a large amount of leftover food, the smell of illegal drugs, or the carpet being used as an ashtray. There is also a risk of large amounts of garbage being scattered around the room. Floors, walls, ceilings, door handles, etc. may be sticky with grease from cakes, etc.
