A common medical disorder in which a cantankerous, old, senior citizen will not stop swearing. Usually directed toward ungrateful "youngsters" meaning anyone from 1 to 55 years of age.

The reasons behind this ailment are quite simple. They've lived long enough that they no longer give a shit who they annoy. So you damn well better listen, you ingrate, or you're gonna get a cane upside your head.

Also known as G.P.D.
Example 1

Person 1: Man, can you believe Craig's creepy uncle? I was just walking by his room, minding my own business, when he poked me with his cane and called me a no good poncy faggot.

Person 2: Yeah dude, he's got a bad case of G.P.D. I'm getting him Brad Goodman's self-help video this Christmas.

Example 2:

Doctor: I'm afraid it doesn't look good Mister Daniels. You have an advanced case of Geriatric Profanity Disorder, and I'm going to have to advise immediate euthanasia.

Mr. Daniels: Speak up you pompous son of a bitch!

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.
Samantha: "Grandma, how long have you been lying on the floor this time?"

Grandma: "Sweetie, I'm so glad you came along when you did."

Samantha: "Please Grandma. No more Geriatric Thumper Dance, OK?
