RC using a form of bad language (7)

Ross

I believe the answer is:

cursing

'bad language' is the definition.
(thesaurus)

'rc using a form' is the wordplay.
'a form' is an anagram indicator (another form of the letters).
'rc'+'using'='rcusing'
'rcusing' is an anagram of 'CURSING'.

'of' acts as a link.

(Another definition for cursing that I've seen is " Using bad language".)

I've seen this clue in The Globe and Mail.
