BBN 

Derived from the better known "brb," this is used to suggest when a person will be back but cannot be certain when they'll be right back as they anticipate other circumstances will delay them from making a speedy return. In the most extreme and rare cases, they will actually "bbn" also known as "be back never."

I'm going to take a shower, Bbn.
I need to do my readings, Bbn.

BBN 

BBN is a signature used by two ninjas who frolic in the Francis Parker school. Standing for "B-Break Ninjas", the term BBN has become a widespread signature throughout the school. During B-Break, these skilled ninjas set up scavenger hunts for other students to enjoy. A wonderous and splendid prize resides in a certain location around the school.

A conversation from a BBN to another BBN:
"yo. Kathryn. do you haz the hat?!?"
"lemme open the locker and get it"
"WOOT. i'll join you. ima finish my activia first, though."
"mmk."
"we are soooo cool"
*high five*.
