A form of throat singing in which you make Goblin-like noises to emulate heavy bass noises common in dubstep.
Did you here my mans Grime-step over there?!?

Yea, he sounds like a goblin with throat cancer.

Get the Grime-step mug.
Some weird cringe-worthy dude found a way to make beat-box sounds like choking and vomiting, basically it's just annoying noise.
Is he puking, or having a Tourrette syndrome? Nah, that's grime-step, you degenerate.

Dubstep music that is so freaking dirty and has breaks that are just absolutely GRIMEY!!! hence the term grimestep as a sub-genre of dubstep...
"Did you just hear that break??? Fucking FILTHY!!! Straight up GRIME-STEP!!"
