I grew up around an old black fellow that had a number of sayings that I heard only from him. The only one that comes to mind right now is one he used often when talking about anyone that wasn't bright, honest or sincere. He's say something like, "That boy ain't twissed (meaning 'twisted') tight." He seemed to use the term for more meanings than what I presumed it came from which was the expression saying someone "had a screw loose" meaning crazy or odd-acting. We used to get really amused at his way of talking, especially since he would occasionally carry on conversations with himself, so I guess he was "twissed tight" himself.

He was a nice, friendly old fellow though, always willing to help in a pinch, so I guess we just considered him to be a little eccentric.
