Take care in Toledo partying with Philip Pirrip (6-3)
I believe the answer is:
toodle-pip
'take care' is the definition.
(I've seen this before)
'toledo partying with philip pirrip' is the wordplay.
I cannot really understand how this works, but
an anagram of 'toledo' is 'toodle' which is located in the answer.
'philip' could be 'pip' (can be a nickname for Philip) and 'pip' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for toodle-pip that I've seen before include "Farewell (informal)" , "Farewell remark - dipole top (anag)" , "Goodbye (dated)" , "so long" , "Take care" .)
