US sailor to pull up for each big sweet lolly (3-7)

I believe the answer is:

gob-stopper

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

'big sweet lolly' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'us sailor to pull up for each' is the wordplay.
'us sailor' becomes 'gob' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to pull up' becomes 'stop' (I've seen this in another clue).
'for each' becomes 'per' (per person).
'gob'+'stop'+'per'='GOB-STOPPER'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
