The title uses BF6, the shorthand fans use for Battlefield 6, while the sound itself is a short dramatic sting in the style of a cinematic reveal cue, similar to the Inception Button effect that became a shorthand for tension online. Short clips like this spread through gameplay edits, montages and reaction videos because they need no explanation and fit neatly before a cut. At just two seconds long, it is easy to reuse, instantly recognisable, and still effective for signalling that something surprising, embarrassing or important is about to happen.
