Not up means when your opponent hits a dropshot and you get it on the second bounce instead of the first.

Thanks. I'll call that sometime and see if anyone knows what I'm talking about.

Yeah, when a chair umpire calls it, he says 'not up' instead of 'double bounce'. 'Not up' is also used by people who played in the 70s or have read the USTA rulebook, which uses the more formal expression 'not up'. Oh, and guys who've done official/linesman training.
