Boy+and+Pal

Boy
 * frequently used among the three men in the house
 * has two contextual meanings. One to refer to a physical young male, the other used as an expression of excitement.
 * used when Willy, Biff, or Happy are feeling excited, pumped up
 * "Terrific job boys" "No boys. Boys!... Tell my boys Ben."

Pal
 * Used by Biff and Willy when talking to Linda
 * For Biff - used to calm or appease her mother. Seems nearly derogatory as he is addressing her as his equal when she should be in a sense superior to him.
 * For Willy - expression of his love or his consideration of her as an equal.
 * Biff when trying to appease her mother: "I was on the move. But you know that I thought of you all the time. You know that don't you pal?"
