Know any good secret handshakes?

Factual Questions

Do the Masons. Oddfellows, Improved Order of Redmen, etc. have secret handshakes?

And if so: since a handshake is pretty much an automatic motion - how do you discern when it takes a secret-signal departure? And what if the recipient has a frat-boy worldview and he misinterprets it to be this sort of handshake: http://www.landoverbaptist.org/news0101/shake.html

Though I’m no longer a Freemason, I won’t reveal the grip out of respect for the fraternity. It’s merely a silent conversation; “I’m a Mason, are you?” “Yes.”

Same with my fraternity’s signs and such: They’re often inobtrusive in a way that isn’t easily differentiated from a normal activity unless you know what you’re looking for–a gap between fingers, angle the hand is held at, I dunno, maybe even how many times one shakes their hands. Particular turns of phrase when greeting or responding to a greeting (“Are you a ‘x’?” might have a particular yet ordinary-sounding response), color-symbols (more common in gangs these days) or shapes/designs (a simple drawing compass or square have a lot of meaning to certain societies when arranged correctly, and I use this example solely because it’s public =P)

All hypotheticals of course, since the point of secret signs is that they’re secret. =P

Great website!!! Boy, am I ever glad to discover that secret handshake. I will sleep better tonight. Incidentally, 40 some-odd years ago, a friend of mine joined a prominent fraternity, and, as I’m sure many many guys do, immediately - well, after a bunch of beers - showed us all the secret handshake and told us the little greeting prelude that goes with it. I haven’t seen him in years (maybe his head exploded for having broken the code of silence), but I showed a different friend and for 40 years we’ve been greeting each other with that handshake.
I could probably tell if someone else was trying to slip me the grip by the way he held his fingers and hand. And, boy, he better not try to give me that homo grip - or I’d tell my friend’s fraternity brothers and they’d whip his ass. xo, C.
