oyaji? What does that mean exactly.

old man or dad

Game Japanese and real Japanese aren't always in synch.

I have a question about "oyaji". I know what it means and all, and I randomly use it with my own father jokingly. My question is the actual speaker to use "oyaji". Is it common for a daughter to use it towards her father, or would that be considered disrespectful or "masculine" for a female speaker?

At least in Kansai I hear men and women use it when talking about their father （家のおやじは。。。）.
