I believe the answer is:

miss the boat

I'm a little stuck... Click here to teach me more about this clue!

'let slip' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'girl eat both bananas' is the wordplay.
'girl' becomes 'miss' (term of address for an unmarried woman).
'bananas' indicates an anagram (bananas can informally mean crazy).
'eat'+'both'='eatboth'
'eatboth' is an anagram of 'theboat'.
'miss'+'theboat'='MISS THE BOAT'

'of a' acts as a link.

Can you help me to learn more?
