'mocking' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'kicking mate they collapsed' is the wordplay.
'collapsed' indicates an anagram.
'kicking'+'mate'+'they'='kickingmatethey'
'kickingmatethey' with letters rearranged gives 'TAKING THE MICKEY'.

'and' acts as a link.
