Your father.

NOTE: While "the old man" refers to your father, "the old lady" refers to your wife or girlfriend, not your mother. Calling your mother "the old lady" is considered disrespectful.
Darth Vader: "Luke, I am the old man."
Luke: "I know you're old. Please stop distracting me while I'm trying to kill you."
Darth Vader: "I didn't say I am AN old man, I said I'm THE old man. As in yours."
Luke: "Oh shit dude, for reals? You're my dad? That's a bummer, considering that you're like the most evil person ever and I've dedicated my life to trying to kill you."
Darth Vader: "I know this must be a tough time for you son. There's a family reunion next week though, and I'd be delighted if you would come with me and meet your Uncle Jimmy and Aunt Susan."
Luke: "Gee...um...dad. I don't know, I'll have to think about it."
Darth Vader: "Ok, I understand. In the meantime, quit trying to bone Princess Leia. She's your sister."
Luke: "DAMN! Glad I used a rubber!"

Army term referring to the commander of a unit. Usually used for a colonel or general, but can be used for a captain (who would be a company commander). Since most company commanders are still in their 20's in the Army though this isn't a common use.

Its usually a term of respect, but many times just used as to refer to the commander without any judgement of respect or disrespect. NOTE = this term is never used in the presence of the old man / commander.
Soldier 1: I heard someone call the barracks to attention, sup dawg?
