When you say something you did that was super awesome, but don't want to be a total cocky dick about it, you say this. Just to let people know what you did was great, but you're not too arrogant about it.
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.
