Drags Irma out for the carnival (5,4)
I believe the answer is:
mardi gras
'the carnival' is the definition.
(Mardi Gras is an example)
'drags irma out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'drags'+'irma'='dragsirma'
'dragsirma' anagrammed gives 'MARDI GRAS'.
'for' acts as a link.
(Other definitions for mardi gras that I've seen before include "Shrove Tuesday celebration" , "pre-Lent festival" , "The lead up to fast" , "Shrove Tuesday carnival" , "Day for 9 acrosses" .)
