A girl who acts like a bro, but is obviously a girl. Has many variations such as a pushup bra (those who try to maintain their femininity) or a sports bra (those who don't mind being considered a guy sans the male genitialia).
Sydney F is a total sports bra ever since she took pe softball class so seriously.
Yeah, well Christine Con might work for the baseball team, but she is still a total push-up bra.
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'> ).
