reverse party 

A spontaneous party in someone else's house or room when the people are home and not expecting it.

Popular at weddings where some core friends go to sleep and you bust into there room late night and party in their room, despite their desire to be sleeping.

Mark was awoken by a reverse party in his hotel room at 3am.

Reverse Party Favor 

The horrifically stupid act of ASSUMING that the white powder on the floor is spilled COCAINE from the night before; then tenaciously SNORTING it off the ground with a 3" straw the next morning; an idiotic effort to beckon the energy to clean up an abandoned party mess left at your house; Only to quickly and painfully realize it was NOT COCAINE, but was DEFINITELY old, dried, dog urine soaked potpourri scented CARPET REFRESHING POWDER from who knows when.

So, I only ever got duped by a Reverse Party Favor ONCE, and will never, EVER, snort ANYTHING off of the ground without tasting it first.

Reverse Housewarming Party 

Instead of making people bring you gifts. You make them take all of your junk.

Examples of stuff you'd get rid of in a Reverse Housewarming Party: DVDs you don't watch anymore. Books you don't read anymore. Cloths that are out of style.

Reverse surprise party 

A party in which, instead of the person/people of honor being surprised, the guests are surprised.
