Name given to a fully erect penis which shrinks to almost nothing after a particularly sickening or hurtful event during lovemaking.

So, I was banging away, when my dick came out on the downstroke and hit her pudenda on the upstroke. The grouchy turtle would not let me get any more that night.

-OR-

She queefed while I was eatin' her. My proud peacock became a grouchy turtle after that mess.
