My Dad called me ugly....on Facebook and in real life...?

[Christen]

My Dad and I have this running joke thing where he calls me names and, in return, I get to call him names.

But in your case, it may or may not be because he simply doesn't know how to deal with you. My grandfather is A LOT like that. He insults me all the time and acts like its a joke, and sincerely believes its funny.

Tell him he needs to stop if he's serious, and if he thinks he's only joking let him know that you don't find it funny. If he cares enough, he will stop.
