Enter with pint and I'm getting rowdy and cheeky (11)
I believe the answer is:
impertinent
'cheeky' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for impertinent that I've seen before include "Not showing proper respect" , "of no relevance" , "Cheeky" , "Fresh" , "Rude" .)
