Maybe Thor's not given enough bangs for his bucks? (5-7)

Ross

I believe the answer is:

short-changed

'not given enough bangs for his bucks?' is the definition.

I don't understand how the remainder of the clue works.

(Another definition for short-changed that I've seen is " Cheated (by cashier?)".)

I've seen this clue in The Guardian.
