Party Fail 

This is an interjection cried out at the sight of a party foul so horrible that it abruptly ends the party.

There are a number of ways to commit a party fail, but the most effective is by punching a wall while yelling "Reagan Smash!" or "Party's OVER!" or "I'm a douche!"

You may as well yell the last one, because by committing a party fail, you will be called a douche. Forever.

Brian and Chad tried to end the party with their words, but what really ended it was Sean punching a hole in the wall and yelling "Party's OVER!" That douche committed an epic party fail.
