Brbr Deng is an onomatopoeic representation of the percussive slap-bass intro to the song 'Dig' by the American nu-metal band Mudvayne. Performed by bassist Ryan Martinie, the distinct metallic sound gained viral status on YouTube and social media decades after its original 2000 release. The meme typically features footage from the 'Dig' music video, often edited to emphasize the aggressive 'brbr deng' sound through subtitles or rhythmic loops. It serves as a tribute to Martinie's unique technical skill while simultaneously poking fun at the high-intensity, chaotic energy of the nu-metal era.
