"I could take it or leave it" (3)
I believe the answer is:
meh
'i could take it or leave it' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for meh that I've seen before include "Not much cop" , "Unexciting (modern slang)" , "am I bovvered?" , "expression of indifference" , "Who cares" .)
