People don't believe me when I say my mom's a palm reader in New Orleans. It's also called Chiromancy.
oh i didn't know that, i have always wanted to get my palm read
people who do it are called either pamists, palm readers, hand readers or even hand analysts but I like chirologist term a lot.
i have never heard that term. apparently its very old.  It is said to have been practiced in very early times by the Brahmins of India and to have been known to Aristotle, 
That's right, it actually comes from the term "kheir" in Greek meaning hand and "manteia" meaning divination. You can foretell someone's future this way.
