Roughly made to be cheeky (4)
I believe the answer is:
rude
'cheeky' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rude that I've seen before include "Insolent" , "Robust - roughly made" , "Impolite; basic" , "Offensive; unpolished" , "Impolite - simple" .)
