I don't know what could make the guy overemote (5,3,2,5)
I believe the answer is:
youve got me there
'i don't know' is the definition.
(I've seen this before)
'could make the guy overemote' is the wordplay.
'could make' indicates anagramming the letters.
'the'+'guy'+'overemote'='theguyoveremote'
'theguyoveremote' anagrammed gives 'YOUVE GOT ME THERE'.
'what' acts as a link.
(Other definitions for youve got me there that I've seen before include "What was said to the successful guide" , "what the passenger eventually said" , "what you can say after being given lift" , "I am stumped" , "I haven't the foggiest" .)
