Intense itching of the skin, often seen after working in the yard. Often in places in the yard where cranberries are known to grow. Most notably experienced by Ben Cranston when he can't reach his back.
Ben: Dang, I've got a bad case of the Cranberry Itch!
George: You've been out in the yard all day. Of course you got it.
Ben: (scoffs) Listen, Riker, don't do me this way. I need some calamine lotion, fast!
Liv: Ben, have you been in the Cranberry again? I told you you'd get Cranberry Itch if you go out there.
Ben: Yeah, and it's killing me. Scratch it for me, would you?
