Way overcharge (5)
I believe the answer is:
gouge
'way overcharge' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gouge that I've seen before include "A chisel; force out" , "Force out brutally" , "Force out with implement" , "Make (a rough hole) in a surface" , "Make a hole or groove" .)
