If you have no idea what a phrase like guro hentai grind means, then you should probably run away screaming.
If you hear that phrase and ask with glee "Did they sample a blender?" yes, yes they did my friend.
This is a laugh, a million atrocities, and sadistic glee fit only for those into the filthiest grind has to offer. I raise the horns and voice my support of this nonsense.
