The concoction drunk at weddings, etc. after someone insults waiter or busboy (usually latino) who then spikes punch with lighter fluid.
Damn that emergency room was jumping cause of that Jew wedding celebrating with that Mexican kidney punch!

The act of hitting some body so hard that your fist breaks their skin and you grab their kidney and pull it out.
Fuck, that kidney punch looked like it hurt!
