megacrush 

When a girl has a crush on you, but you are too noobish to realize, or you are too shy to do anything about it. This girl will hang out with you and give you all the opportunities in the world for you to make your move, but you never will. This will only inflate the megacrush.

Unfortunately, you will only find out about the megacrush well after the window of opportunity. This information will haunt you for the rest of your days.
1997
Girl: Hey, I just rented Scream, and I'm too scared to watch it by myself. Do you want to come over and watch it with me?

MegaFlush 

A MegaFlush can be performed when competing (in teams) towards getting the most work units done in a distributed computing project.

To perform a MegaFlush one can use processing power to calculate work units months before a competition starts. When the competition begins the work units are submitted and thus count for the competition. This is used to give yourself or your team an unfair advantage.
Any one team that performs a MegaFlush will be banned from the contest.
