1. Suppose a character is talking to his younger brother:
"Hey Runt. Come here."
Should "Runt" have a leading cap? If it is a long-standing nickname, I'd say yes. But even if it is being used for the first time, I'd still say yes. "Runt" is being used as a replacement for the brother's name. (i.e. proper noun)
2. What about:
"Hey dude. Come here."
Should "dude" have a leading cap? I'd be inclined to say no if the character refers to all sorts of guys as dudes. (i.e. a generic label)
3. If I'm correct about (1) and (2), then where do you draw the line?
