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."

BS is an acronym used by some Android and iOS gamers to refer to Brawl Stars, a battle royale game developed by Supercell. The game features various gameplay modes for solo and teamwork play, including three vs. three battle gameplay.

Supercell released an open beta version of BS in June 2017 and officially released it in December 2018. While the game has become popular, only iOS and Android games will use the acronym.

An acronym used on diabetes blogs and forums and refers to the level of sugar in the body's blood.
