butt donut 

An inflatable ring cushion for old people with bad joints or pathetic losers who crack, chip or bruise their tailbone/butt.

When Brigitte was sent careening down the snowy hill and smashed her tailbone into some rocks at the bottom, she eventually had to buy a butt donut to sit on for 6-8 weeks.
