BYOB is a track by System of a Down from their 2005 album Mezmerize, written as an anti-war protest song whose title is short for Bring Your Own Bombs. The song became one of the band's biggest hits, winning a Grammy for Best Hard Rock Performance and remaining a staple of mid-2000s alternative metal. Its direct, accusatory lyrics have kept it relevant in online edits about inequality, war and unfair treatment, where a single shouted line can carry the whole argument of a short video.
