But I cannot be mad at anything named "Crabcore".

Go to 2:35.

"But, unlike all the other genres covered in this column, crabcore isn't defined by sonics or BPMs or lyrical content, or tied to a geographic location. Crabcore is defined by the body contortions of the band's guitarists when they perform."
