In her case it would be "Congenital Liar"
@Wingnut True. She reminds me of a local guy I know. Lying is his kneejerk reaction to everything,and the instant he says it,he believes it himself. He once told me he used to date Juice Newton in high school,and was constantly saying "Juice used to tell me,......" some bizarre thing or another. So I went home one day and looked her up on the web.
The next time he said something like that in public,I asked him why he wasn't in prison as a child molester if that were true,since she would have been 9 years old when he was a senior.
He wasn't the slightest bit embarrassed. Just confused,and you could see the confusion in his face. He had said it a couple of times,so now HE believed it himself.
FWIW,I haven't heard him make that claim since.
