Why only use hand signals??
When I'm diving with my wife and we need to say Mega-super-cool or something about that level, we start grunting or "whale singing" (I must warn you, though: I'm not Dory and I can't speak whale!). At the beginning we couldn't make much noise, but with a little practice you can make your buddy hear you.
The "coolness level" determines the frequency and pitch of the grunts, the whale singin reserved for the veeeery best.
On a side note, I once had two ladies that were teachers in a school for the deaf (or whatever politically correct euphemism it is called), and after the first OW dive they decided to stop that underwater hand-blabbling. As the signature of somebody in this board says, "...[being underwater] ...is so silent, you're like a thought"
