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:

"lemme open the locker and get it"
"WOOT. i'll join you. ima finish my activia first, though."
