Sam We Am.
First of all, people ALWAYS ask you if your name is short for something.
It probably is! Samuel or Samantha. BUT CALL ME SAM, PLEASE.
Lionsgate
Also, people love to call you "Sammy" like it's cute or something. It's not.
Unless you like being called Sammy, which is totally cool! Your choice.
Lucasfilm
In addition to being a sometimes-annoying nickname, "Sammy" is also slang for a sandwich. Which is just plain rude.
But we still love sandwiches.

It was TERRIFYING when you were a kid and your parents called out your full name because you were in trouble. "SAMUEL" and "SAMANTHA" just sound scarier!
