Reminiscent of Thumper the rabbit from the Bambi cartoon, it is the practice unique to elderly people in which they quickly tap their foot on the floor several times in rapid succession immediately prior to raising that leg off the floor so that they can quickly slide on that side of their underwear, pajamas, or pants before falling. Contradicting the apparent belief underlying this behavior, studies by gerontologists have concluded that the Geriatric Thumper Dance is mostly ineffective in preventing old folks from losing their balance.
