tear limb from limb

Either a disgusting way of murder, or to roast someone beyond their will to live. No matter which one you use, somebody's gonna be destroyed.

"Did that bitch just touch my celebrity crush?!?! I'm gonna destroy that slut if I meet her! The only acceptable murder is to tear limb from limb!!!" - 14 year old me at some point
"Did that rich kid just roast you?"
"Yeah, but I'll tear him limb from limb at some point."
