Slicing this fruit could make chap pee (5)
I believe the answer is:
mango
'slicing this fruit' is the definition.
'mango' can be an answer for 'fruit' (type of fruit). I'm not sure about the rest of the definition.
'chap pee' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'pee' becomes 'go' (I am not sure about this - if you are sure you should believe this answer much more).
'man'+'go'='MANGO'
'could make' is the link.
Can you help me to learn more?
(Other definitions for mango that I've seen before include "fruit tree" , "Type of fruit" , "Yellow-fleshed fruit" , "No, Mag has the odd fruit" , "product" .)
