Terms of Endearment and Teenage Boys

Rob says that I should stop referring to Teen Son as "Sweetie." He says it's not masculine enough and no teenage boy should have to endure such verbal abuse. I asked Teen Son and he said he doesn't mind if I call him Sweetie. However, Rob continues to insist that I should find a term of endearment that is more manly (grunt, grunt). I wonder if "Dirt Bag" would work.
