Bravo and Sierra are two of the military's words used to prevent misunderstandings in radio transmission. They stand for the letters B and S in the same way that Alpha means A and X-Ray means X.

Using "I call bravo sierra" is a more articulate and less crude way of saying "I call bullshit". It also can be a coded way of letting your friends know what you think while keeping the clueless out of the circle.

The phrase has been popularized by the XM Satellite radio team of Opie & Anthony.

Herbert: "I graduated Princeton with a 4.0 cumulative average."
Jimmy: "Did ya? I call bravo sierra."

Sierra Bravo 

Phonetic speaking of the letters SB, used to mean Shitbag. Spoken often in the presence of shitbags so that said shitbags do not realize that they are being called out.

Commonly used in the military, e.g. Navy, to refer to those who lack the ability to show any discipline, bearing, character, honor, care, or commitment to the fact that they themselves are a member of the Armed Forces.
