Tremendous hooter squeezed by husband in middle of night (7)
I believe the answer is:
howling
'tremendous' is the definition.
(howling can mean tremendous or great)
'hooter squeezed by husband in middle of night' is the wordplay.
'hooter' becomes 'owl' (owls hoot).
'squeezed by' means one lot of letters goes inside another (some letters squeezed into others).
'husband' becomes 'h'.
'middle of night' becomes 'G' (middle letter of 'night').
'h'+'in'='hin'
'owl' inserted inside 'hin' is 'howlin'.
'howlin'+'g'='HOWLING'
(Another definition for howling that I've seen is " (Dog) baying; Cold Comfort Farm village".)
