I don't give a fig.
Seriously, this is not a name. It'd be like naming somebody Banana or Watermelon.
I can see somebody getting called Fig because, say, his last name's Figueroa or Figgenbottom or something, or even if the last name is Newton.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
