Would he be 'Racey' if he called him "Fatty Boom-boom"?

I don't know, but he'd definitely sound like a toddler if he called him that.

Would Han be considered "racey" (which isn't a word. "Racy" is though, but means something different entirely) if he called Lando a "darkie boom-boom"?

And to answer your question on the first bit, yes, Han was obviously taking a jab at the appearance of Jabba and his species when he said that. Is that even debatable?

Some of you guys are trying to drive your point home by saying that these comments are based on appearance, and therefore nothing to do with race (species). What?! The "N" word is a comment on color (appearance). How can we even compare calling a guy with glasses "four eyes" with calling an Asian "slant eyes"? They are not even in the same ball park! All racism has ever been based on has been appearance, "They don't look like us; so they are not as good as us".

This actually comes along again in the prequels Padme reacts to Anakin killing an entire village of Tuskens, including the women and children with far less disgust than many of us on these boards might react to hearing about someone getting mad and killing a puppy. Later when Obi-Wan tells her that he killed a bunch of young Jedi children (mostly humanoids that look like her) she freaks out and tearfully says that it isn't possible and that he would never do such a thing. Again, this is simply just bad writing, but you can't really ignore the fact that it is implying that the Tuskens' lives were less valuable in her mind than the lives of those humanoid Jedi that resembled her.
