Brand New Attitude. Derived from the show Bojack Horseman, where Bojack listens to motivational tapes to get him out of his depressive funk. He tries to adopt a brand new attitude that he can change, get healthier, and have a positive life. Unfortunately his tragic character flaws will not allow him to overcome his severe childhood trauma and appreciate the positive things in his life (fame, health, fortune, friends, independence, family, and love interests).

BNA is also the abbreviation of the Nashville International Airport, oddly enough.

An alien from another dimension that is both black and sarcastic. Yet extremely fast, this creature is very weak. Be cautious around BNA's because they may tickle your asshole or throw XBox controllers at you in pure fury. His main oppositions are XBox malfunctions, DDD's, abusive men named Sal. Well-known quotes: Betta not, oh oh oh, WHAT A FFAGGOT, I definitely just....., and MAGICAL SNIPER!!!!

BNA is a acronym for "Broke Niggas Association"
