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.
The use of profane language in everyday conversation. ( Not used as an insult, out of anger, or confusion, etc.)
" What did you do today?"
" Just sat around the fuckin' house, watched some shit on t.v., dicked-off on the interwebs."
"why the foul language? Are you mad at something?"
"No, just a littlecasual-profanity"
