The phrase comes from Cypress Hill and their 1995 track Boom Biddy Bye Bye, released on the album III Temples of Boom during the group's peak West Coast hip hop years. The hook was built to be chanted and remembered, so short cuts of it travel easily outside the full song. Online, editors lifted the two second line for soundboards and meme edits, where boom signals an impact and bye bye turns it into a dismissal. Its brevity and familiar rhythm keep it in circulation.
