A shortened version of "Samantha" used by women who don't take themselves too seriously. Sams are generally high-energy, full of laughs, but are not immediately liked by people who meet them for the first time. They can seem quiet, but have a deeply loving and caring side to them. They can be overly chatty, and often like to gossip, but would apologize profusely if the recipient ever found out what they said. Sams are often athletic, and thus extremely attractive women who have many suitors. They smile wide, but internally worry about what people think of them. A Sam is someone who takes a little bit to get to know, but once you do, they'll never leave your life.
"Oh, Sam - she's such an odd girl but I love her anyway!"
