Commotion in Idaho, Ohio quite the reverse! (3-2)
I believe the answer is:
hoo-ha
'commotion' is the definition.
(I know that commotion can be written as hoo-ha)
'in idaho ohio quite the reverse' is the wordplay.
'in' indicates a hidden word.
'the reverse' is a reversal indicator.
'ahooh' is hidden in the letters of 'idaho ohio quite'.
'ahooh' written backwards gives 'HOO-HA'.
(Other definitions for hoo-ha that I've seen before include "Fuss (informal)" , "Kerfuffle" , "Commotion (informal)" , "Fuss, commotion" , "great deal of fuss" .)
