A bet exclusively for boys. The simple terms are that the winner gets to hit the loser in the balls. Very high stakes bet which few dare to take.
Example 1:
Jon: What happened to Max? Why is he on the floor?
Mitch: Oh he just lost a balls bet with me
Example 2:
Austin: Balls bet that I can beat this level.
Ben: Deal.
Austin: *beats level*
Ben: Shit. Wait-not too hard-aaawwwww!
Jon: What happened to Max? Why is he on the floor?

Facebook balls refer to the harsh, rude things that people might say on Facebook that they wouldn't say in person.
Rob posted on Facebook that Larry's girlfriend is a total dog. He would have NEVER said that to his face. He's got some big FBB's (Facebook Balls). Then Larry posted back that he was gonna punch Rob in the face. The FBB's must be contagious.

Midnight (0000 in Military time) to 4 watch. The first watch of the day's rotation. NOT unique to any maritime academy. In fact, it is a pretty common term in most branches of the military. I've also heard it called the Balls to Forever watch.
