Applaud role reversal? That’s rubbish (8)

Ross

I believe the answer is:

claptrap

'rubbish' is the definition.
(thesaurus)

'applaud role reversal?' is the wordplay.
'applaud' becomes 'clap' ('clap' can be a synonym of 'applaud').
'role' becomes 'part' ('part' can be a synonym of 'role').
'reversal?' says the letters should be written in reverse (I've seen 'reversal' mean this).
'part' reversed gives 'trap'.
'clap'+'trap'='CLAPTRAP'

'that's' is the link.

(Other definitions for claptrap that I've seen before include "Meaningless, insincere or pompous talk" , "Pretentious talk used to win applause" , "Contrived but foolish talk" , "Balderdash" , "Absurd or nonsensical talk or ideas" .)

I've seen this clue in The Times.
