ねちょっと聞いて。

Phil: Guess what?

Students: What?

Phil : I'm gonna write 6-7 lessons this month!

So "ねちょっと聞いて" literally means "Hey, listen a bit" but in English we say "Guess What?".

The answer is always "What?" after which the person usually tells you his big news.

For example:

A: Guess what?

B: What?

A: I'm getting married~!

B: Wow, congratulations!

But sometimes people say:

A: Guess what?

B: What?

A: Go on guess!

B: Umm, You're new girlfriend is an alien?

A: No, come on make a serious guess!

B: Huh, I don't know. I give up.

A: I won a trip to Italy!

B: Wow, great!

So the next time someone asks you "Guess what?" remember to reply "What?"!

Have a great weekend,

Phil
