not too bright. when u or someone does something that is just not the smartest move. often its yourself or a friend who just did something really dumb yet they aren't normally dumb. kind of like a blonde moment if u will.
dude, u just wiped out in the middle of the street and broke the heel on your shoe in front of that hottie u were trying to impress. totally NTB.

NTBS is playlist slang that stands for "Not To Be Shuffled". Meaning, a NTBS marked playlist is not to be shuffled and should be listened to in order, from beginning to end.

Get the NTBSmug. Not The Boys
A group of young men who are not a part of the "boys" group because, the boys, are douche bags. Thus, Not The Boys, or "NTB" are not douche bags or assholes and are far superior to the "boys".

Damn, the boys are such assholes to everybody, thankfully I'm apart of NTB, the far superior group of friends. #LongLiveNTB
