Pet like a snake, say, suitable? (5,3)
I believe the answer is:
hissy fit
'pet' is the definition.
I know nothing about this answer so I can't tell whether this works.
'snake say suitable?' is the wordplay.
'snake say' becomes 'hissy' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'suitable?' becomes 'fit' (similar in meaning).
'hissy'+'fit'='HISSY FIT'
'like a' is the link.
Can you help me to learn more?
(Another definition for hissy fit that I've seen is " American's temper tantrum".)
