Some person's laughter is offensive (9)

I believe the answer is:

onslaught

'offensive' is the definition.
(thesaurus)

'some person's laughter is' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ONSLAUGHT' can be found hidden inside 'persons laughter is'.

(Other definitions for onslaught that I've seen before include "Aggressive action" , "Hunt goals (anag) - offensive" , "Sally" , "Destructive attack" , "Assault" .)

I've seen this clue in The Telegraph.
