A clever coverup word that can be used to describe any part of the human anatomy. Especially useful if there are churchies nearby who may be offended if you say "Dick, pussy, ass, titties, or ballsack."
"If you don't quit pestering me, I'm gonna kick you in the gizzard!"
"I worked them gizzards over big time in the sack last night!"
"My gizzard hurts, I better go see Dr. Kevorkian."
"She had some fine looking gizzards before she made a mess of the bottom."
