Me and my buddies were out drinking one night and started talking like Native Americans, so we figured we should give ourselves some Native American drinking names. We ended up with Chief Grand Cherokee, Cheeko, P.S.(Paint Sniff), and then we could'nt find one for me. Someone then mentioned that the math acronym to remember trigonomic ratios sounded kind of like a native name, so ever since my nickname has been Sohcahtoa(So-ka-toe-ah), I get called it even when I'm not drinking, but I don't mind.
