Leave to get fruit and act wildly (2,7)
I believe the answer is:
go bananas
'act wildly' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'leave to get fruit' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'to get' says to put letters next to each other.
'fruit' becomes 'bananas' (I've seen this before).
'go'+'bananas'='GO BANANAS'
'and' is the link.
Can you help me to learn more?
(Other definitions for go bananas that I've seen before include "Flip one's lid (sl.)" , "Become mad or furious" , "Show enthusiasm" , "Be extremely excited" , "Lose one's cool" .)
