This is a bit of an inside joke. Eddie and his friends create a little club called the "Burger Boys," and the purpose of this club is to try out burgers from different restaurants in their city. Eddie's famous in the series for having a love for cheeseburgers. Thus, his mother is referring to this when she calls him "cheeseburger boy."
