Crabcore

Crabcore is a type of music and performance style that started in the early 2000s. It's a type of heavy metal music that is known for its use of fast drumming, screaming vocals, and guitar riffs that are often played in sync with each other.

The name "crabcore" came about because the performers often seem to be crab-walking or crab-like in their movements while playing music. This is because they move sideways with their arms and legs, which looks like the way crabs move.

The music and lyrics are often aggressive and meant to be performed with high energy, including jumping and shaking one's head around.

Some people love crabcore, and some find it to be silly or strange. But regardless of one's opinion, it's a unique and exciting form of music that has a loyal following.
