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

'spread gossip' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'knockout model and husband tried swinging' is the wordplay.
'knockout' becomes 'dish' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'model' becomes 't' (Ford Model T car).
'and' means one lot of letters go next to another.
'husband' becomes 'h'.
'swinging' indicates an anagram.
'tried' anagrammed gives 'edirt'.
'dish'+'t'+'h'+'edirt'='DISH THE DIRT'

Can you help me to learn more?
