There is a scene in the movie Beautiful Girls:
Marty: Are you OK?
Willie: Yeah. Yeah, I'm... Why?
Marty: You seem a little flavored today.
Willie: No! No, I'm cool.
Marty: Cool.
Willie: Yeah. So, tell me something. What do you kids...? What is it you do, kids your age, on the weekend?
Marty: Well, what we've been doing lately is smoking massive amounts of drugs, binging on Entenmann's and listening to Pink Floyd.
Willie: Really?
Marty: You are flavored today.
Willie: Oh, you're kidding?
Marty: The Entenmann's part was true.
Major dictionaries don't have this usage, so I turned to Urban Dictionary which lists it as "distracted, preoccupied, generally out-of-it, not lucid". This definition makes sense in the context, but I am wondering how "flavored" came to mean distracted. Is it a regional or dated usage?
