Somersault hit the roof (4)
I believe the answer is:
flip
I believe this is a double definition.
'somersault' is the first definition.
(synonyms)
'hit the roof' is the second definition.
(both can mean to become very angry)
(Other definitions for flip that I've seen before include "Propel with finger - lose one's temper" , "Throw a wobbly" , "demanding > alcoholic drink" , "Toss - flick - turn over" , "Perform somersault" .)
