a.) when you find out some horrible news, realize something bad has happened to you or your friends, or that you are in a bad situation. Started by Hobbs and Ramey in the summer of 2005, around the time that Ramey wrecked his car. Can be said as "balls on your chin" or any other body part for that matter. If the mishap is extreme, could even be "balls all over your face" or "balls on your car", etc. Often replaced with the word, "Whammy."
Ramey: "Dude, I totally wrecked my car tonight."
Hobbs: "Man, that's balls on your chin..."
