The repleted scrotum after a man who was lucky enough to have multiple orgasms during an hour of mindblowing sex. Named after the "wattle" (the red flesh that hangs off a male turkey's beak) because the wattle is often referred to as a gazzler, since no one knows to call it a wattle.
"Oh man, check out the gizzle-gazzle my girl gave me last night! Touch it too! It's so empty I could keep my keys and wallet in there, like a pocket!"
