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

'curse wildly about some skippers who sink their ships' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'curse wildly about some skippers' is the wordplay.
'wildly' is an anagram indicator.
'about' is an insertion indicator.
'some' indicates the central letters.
The middle of 'skippers' is 'pp'.
'curse' with letters rearranged gives 'scuer'.
'scuer' enclosing 'pp' is 'SCUPPER'.

Can you help me to learn more?
