A girls version of the word bro. A best friend. Something that is always there for support. Even though they can be a little bit uncomfortable at times, life without them would be very difficult.
a. Bras before boys!
b. Ava... She's my bra. She is so supportive!

Bad, Rotten Apple
Something described when a person is worse then just a BA (Bad Apple).

If this person is really bad-ass, they will be a B.R.A. or a Bad apple, rotten to the core.
Whoa, that kid just budged in front of everyone in the lunch line.
OMG! He's such a B.R.A.!

In Dirac Notation of quantum mechanics, the representation of a state. The complex conjugate of a ket. Denoted as <f| where f can be a wave function or a set of quantum numbers. Analogous to a row vector in linear algebra. The name originates from separating a bracket ( <f|f'> ) into a bra ( <f| ) and a ket ( |f'> ).
<nlm| is a bra representation of the Hydrogen atom with quantum numbers n, l, and m.
