Rush to get a drink - and a humdinger it is! (10)

I believe the answer is:

ripsnorter

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

'a drink and a humdinger it is' is the definition.
I can't tell whether this defines the answer.

'rush to' is the wordplay.
'rush' becomes 'rip' (I've seen this in other clues).
'to' becomes 'snorter' (I can't justify this - if you can you should believe this answer much more).
'rip'+'snorter'='RIPSNORTER'

'get' acts as a link.

Can you help me to learn more?

(Another definition for ripsnorter that I've seen is " remarkable product".)

I've seen this clue in the Evening Standard.
