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!
