The phrase comes from Counter-Strike culture, where short callouts tell teammates where enemies and weapons are located. Negev names the light machine gun, while B refers to one of the two bombsites players must attack or defend. Clips built around urgent or badly timed callouts have long circulated in gaming edits and voice chat compilations because they are instantly understood by FPS players. This one survives as a reaction to overpowered pushes, spray heavy defenses and rounds that feel lost before the fight on B even starts.
