“First blood” is a long-running phrase in competitive gaming, used for the first kill or opening takedown in a match. Online, short announcer-style clips of the phrase spread through gameplay edits, meme videos, and reaction posts because they instantly signal that someone struck first. The sound stays popular since it is easy to understand even without context and fits many formats, from shooters and MOBAs to sports jokes and friend-group edits. It is often paired with a buzzer for extra comic emphasis.
