In Suzanne Collins's Hunger Games story, brought to the screen in the film series beginning in 2012, a cannon is fired in the arena each time a tribute dies, letting the remaining competitors know the death toll has risen. The sound became shorthand for elimination as clips from the films circulated online, and editors began lifting the isolated boom for gaming videos, reaction memes, and fan edits. Its staying power comes from that instant recognition: even viewers who have not seen the films understand it as a dramatic, final end.
