Overcharging daft Big Brother lad year in, year out (8,7)
I believe the answer is:
daylight robbery
'overcharging daft big brother lad year in year out' is the definition.
I can't tell whether this defines the answer.
'daft big brother lad year in year out' is the wordplay.
'daft' indicates anagramming the letters.
'year' becomes 'y'.
'in year out' becomes 'y' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'big'+'brother'+'lad'+'y'='bigbrotherlady'
'bigbrotherlady' anagrammed gives 'daylightrobber'.
'daylightrobber'+'y'='DAYLIGHT ROBBERY'
Can you help me to learn more?
(Other definitions for daylight robbery that I've seen before include "Blatant overcharging" , "Extortion" , "A shameless swindle" , "audacious act of exploitation" , "Scandalous" .)
