Hello, back-atcha. (back at you => back-atcha)

1) She's a chow chow.
Sorry. I don't know. Is chow chow a breed of dog? If so, it either means, She's cute or She's not cute.

2) He has got a lot of growing up to do.
He is immature.

3) A phoney phone number.
The wrong phone number. It's not the person's real phone number. For example, Sam gave me his phone number, so I called it and a Mrs Quinn answered. She said no one named Sam lived there. I guess Sam doesn't want me to call him, because he gave me a phoney phone number.

4) Just go with the flow.
Don't try to control the situation; i.e. don't steer the boat, let the boat go with the flow of the river.

5) To be one round of something.
Sorry. I don't know.

6)You'll get the thumbs up for sure.
The OK to go ahead.

7) Blue-eyed boy.
Sorry. I don't know.

8) Out of the blue.
Unexpectedly.
