Gridlock

'Gridlock' refers to a major traffic jam when no one can move. It has also been used the American political scene as if late.

Example:
-Gridlock traffic! Happy Monday.
-Ugh.

Grounded

If you're 'grounded,' it means that your parents have punished you. You can be grounded from your phone, tv, going out, or whatever else your parents decide upon.

Example:
-Why'd you get grounded?
-I stayed out two hours past my curfew.

Good ol' boy

When you hear someone talking about a 'good ol' boy,' it conjures up the image of a guy who lives in a small, rural town, drives an old beat-up pick-up truck with a Confederate flag in the back window (which he sees as a symbol of Southern pride), probably chews tobacco and may or may not have a high school education. They are perceived to be prejudiced and racist. Calling someone this is not a compliment, unless you also happen to be a 'good ol' boy.'

Example:
-I live in New York now, but back home, I knew a lot of good ol' boys.
-Really?

Gold digger

A 'gold digger' is a person who wants to marry a wealthy person. Sometimes it's with the intent of living a better lifestyle, and sometimes it's planned in advance to later get divorced and try to get as much money out of the person as possible. This is why many extremely wealthy people sign a pre-nup (prenuptial agreement) before they get married, which states who gets what in the case of a divorce.

Example:
-I can't believe that 22 year old model married that 80 year old man. Eww.
-What a gold digger! His family must be furious!

To get in the middle of it

'To get in the middle of it' means you get pulled in to an argument between two people that really has nothing to do with you.

Example:
-Mom, she called me stupid!
-Well, she said I was fat!
-Look, you two, that was't nice of either one of you, but I'm not going to get in the middle of it. You two need to figure it out and apologize.

Good luck with that!

'Good luck!' can mean just what it says -- that the person is wishing you well in your endeavor. However, 'Good luck with that,' especially when said with a sarcastic tone, means that the other person doesn't think you're going to be successful at all.

Example:
-I'm gonna go cram for my Philosophy final tomorrow.
-Yeah, good luck with that!

To go off on someone

'To go off on someone' means to tell someone how angry you are about something they did.

Example:
-So what did she say?
-She totally went off on me, saying how immature and irresponsible I am.

Got a minute?

'Got a minute?' is a polite way for someone to ask you if you have time right now to listen to something they want to say. Interestingly, whatever they have to say usually takes much longer to say than a minute, which is why the person asking this question asks. The listener is also aware, and answers with, at minimum, a 5 minute conversation, in mind.

Examples:
-Got a minute?
-Sure, what's up?

-Got a minute?
-Actually, I'm on my way out the door. Can we talk after my meeting?

Get a room!

When a couple is being (overly) affectionate either physically or verbally, someone will invariably say, "Get a room!"  The room they are referring to is a hotel room, which is for the couple to have sex in.

Example:
-I love you!
-I love you more!

Person overhearing conversation -Oh, get a room!
