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

'stroke' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'right moth is wrong' is the wordplay.
'right' becomes 'r' (common abbreviation).
'wrong' indicates anagramming the letters.
'moth'+'is'='mothis'
'mothis' with letters rearranged gives 'imshot'.
'r'+'imshot'='RIMSHOT'

'is' acts as a link.
