Jelly arms

The act of vengeance usually toward a snitch. This act of violence towards another human being is by brutally taking a machete or other such sharp object and whacking both arms of the victim. After severing (but not completely cutting off) cartilage, tissue, etc., the perpetrator then grabs the arms of the victim and shakes them, because many vital structures to the arms have been been cut, the arms are like jelly, hence "Jelly Arms." It is a known act used by Narcoterrorists.
