"You've got another thing coming"
Thank you for reply in advance,
***** NOT A TEACHER *****
(1) I don't know how you used that phrase.
(2) But here is one possible explanation:
TOM: I'm in big trouble. I need $100 right now. Could you lend me a hundred bucks, please?
MONA: What? You expect ME to lend you a hundred dollars? Every day you treat me rudely. You never compliment me. You never thank me. And now that you're in trouble, you come to me for money. Listen here, my friend. YOU HAVE GOT ANOTHER THING COMING!!! = You are not going to get the 100 dollars from me. You are going to get ANOTHER (an + other = one other) thing. That "other thing" is NOTHING! Not one penny from me.
Thank you for your question.

I'll bet a buck that's the context.
It's a song title:
You've Got Another Thing Comin'
One life i'm gonna live it up
I'm takin' flight i said i'll never get enough
Stand tall i'm young and kinda proud
I'm on top as long as the music's loud
If you think i'll sit around as the world goes by
You're thinkin' like a fool cause it's a case of do or die
Out there is a fortune waitin' to be had
You think i'll let it go you're mad
You've got another thing comin'....Judas Priest - You've Got Another Thing Comin' - text písn? - Lyricon.net
No convincing ideas, sorry
(Please take that in the spirit of good humor with which it was intended. It is, indeed, a somewhat unusual expression. Thanks for bringing it to our attention.)
Thanks to all who replied...
The idiom is "You've got another think coming". I BrE it's a response to "I think that....", it means "I am going to tell you something that will make you think differently". It is also used in this sort of context:
"If you think you are going out tonight, you've got another think coming!" Said perhaps to a teenager who should be studying.
