What is your opinion on the opposite? For me that's far more unsettling. I've initiated handshakes with people whose age and home country meant they didn't really have much experience of the Western "firm handshake", always the limp wrist. I don't know whether to shake it, or draw the hand to my lips as courting a princess. Which, I assume, was not one in your repertoire of "intricate hiphop style handshakes".
Jokes aside, more than one family member had felt it important to instruct me in the art of a good handshake as a matter of gentlemanly conduct from a young age, even long after I'd obviously "got it", and I distinctly recall one of my friends suddenly in his mid-20s going from a pathetic one to a really decent powergrip apparently because his boss had told him after a promotion that he ought to work on his handshake. I say this in defense of the one who "actively squeezes", as it may not be macho-signaling so much as over-correction for their past dead fish.
