kidkin
When a child (usually your own, less than 5 years) makes a HUGE doodie in the bowl and forgets to flush the toilet. Then a guest comes over and uses the bathroom and see the "beast" still floating and wonders what you ate for dinner and how bad your manners are.
"My son Jack left a kidkin in the bathroom....then a date came over and saw it and nearly puked. She asked me if I ate an elephant that night...and said that the Lysol spray was empty."
