It's very near to cheek in two ways (3)
I believe the answer is:
lip
'cheek in two ways' is the definition.
'lip' can be an answer for 'cheek' (both can mean insolence or rudeness). I am not sure about the 'in two ways' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lip that I've seen before include "Edge of mouth" , "Rim; impertinence" , "Rim; impudence (slang)" , "Edge; impudent talk" , "Aural impudence" .)
