Everybody involved in crudely menacing verbal abuse (4-7)

I believe the answer is:

name-calling

'verbal abuse' is the definition.
(I've seen this before)

'everybody involved in crudely menacing' is the wordplay.
'everybody' becomes 'all' (I've seen this before).
'involved in' means one lot of letters goes inside another.
'crudely' indicates an anagram.
'menacing' anagrammed gives 'namecing'.
'all' going into 'namecing' is 'NAME-CALLING'.

(Another definition for name-calling that I've seen is " Verbal abuse".)

I've seen this clue in The Telegraph.
