The word bruh has long been used online as a blunt, one-word reaction to something stupid, disappointing or unbelievable, and the short bruh sound became a staple of reaction videos, memes and short-form edits. Stretching it out, as in this clip, turns that quick dismissal into a longer, more theatrical groan, which is why creators keep reaching for it for fails and awkward reveals. Its simplicity is the point: listeners recognise the feeling instantly, even without context, and the extended version makes the joke land harder.
