No, "campy" is an overall feeling, where mannerisms are a part of the whole.
Male homosexually influenced flamboyance and silliness -- that's about as close as I can come to describing "camp." If you rent Priscilla, Queen of the Desert (a fabulous movie, in my opinion) or To Wong Foo Thanks for Everything, Julie Newmar, you'll see a lot of camp.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
