When you've done too much cocaine and your jaw begins swaying back and forth.
"Look at that jaw, he's done way to much cocaine, shnibblies, nar-nar, nar-mellow."

Little girl: "Why is that sweaty guy making that weird face daddy?"

Her father:"Well sweetheart, that's what we call a jiggle-jaw, I'll tell you all about it when your older"
