I'm a little stuck... Click here to teach me more about this clue!

'gosh' is the definition.
(I know that gosh can be written as wow)

I don't understand the remainder of the clue.

(Other definitions for wow that I've seen before include "Expression of amazement" , "that's incredible!" , "Expression of surprised admiration" , "Impress hugely" , "Cor! - huge success" .)

I've seen this clue in The Times.
