Should a fighter ever be referred to as a bum or tomato can?

Every sport has the cream of the crop & bottom of the barrel. Yup, there are tomato cans: Guys who get paid to take dives, who fight just to make a few bucks & guys who actually try but get their buttocks handed to them. They all qualify as bums/tomato cans.

I feel as though the ones who make an honest effort deserve our respect no matter how limited their skills are.

It's the fat slobs and ones who take dives and don't train that I feel comfortable calling bums.
