BS

BS stands for "bulls***," a common American expletive. Saying something is BS is a crass way of saying that thing is unfair or untrue.

Those who are angry and/or skeptical are most likely to call (meaning call attention to) BS, in an attempt to show how they have been wronged or lied to. BS may also be used as a verb, meaning "lie to" or (in less contentious contexts) "discuss idly."
