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

'more vulgar than anyone else?' is the definition.
I can't judge whether this defines the answer.

'is thickset criminal' is the wordplay.
'criminal' is an anagram indicator.
'is'+'thickset'='isthickset'
'isthickset' is an anagram of 'KITSCHIEST'.
