'it' is the definition.
The definition suggests a singular noun which matches the answer.

'scoffing and make yankee shoot' is the wordplay.
'scoffing' is an insertion indicator.
'and' becomes 'n' (common abbreviation for 'and').
'make yankee' becomes 'brady' (I can't explain this - if you can you should believe this answer much more).
'shoot' becomes 'snap' (synonyms).
'n' inserted into 'brady' is 'brandy'.
'brandy'+'snap'='BRANDY-SNAP'

'may cause' acts as a link.
