A 'Bruh Moment' refers to a situation so disappointing, shocking, or awkward that it can only be met with the word 'bruh.' The term gained massive popularity through a viral Vine featuring a sound effect of the word spoken in a low, resonant tone. Historically, it evolved from a specific reaction to a general internet slang used to describe any social blunder or moment of sheer disbelief. Today, the meme often features images of people looking disappointed, exhausted, or the iconic 'Bruh' button, serving as the ultimate digital sigh for the modern era.
