Posttraumatic yapping disorder

A special type of disorder which happens when every single thing the person says is yapping. It usually happens when the said person has consumed too much yapping from other people.

Doctor: I am afraid to say that you have Posttraumatic yapping disorder.
Patient: Oh my god, never have I expected to get such a disorder. You know that all of my friends have the same thing? I think it is pretty funny that we will all have it. Especially my great great friend that is really close which is really funny and interesting because i acctually studied this type of relationship. I think I had this since the day my father left. Sad story, really. One day he got out to get milk and never came back. Anyways, what was I talking about?
Doctor: Please get the hell out of my office.
