Rudeness from oddball seen with Colin (9)
I believe the answer is:
insolence
'rudeness' is the definition.
(I know that insolence is a type of rudeness)
'oddball seen with colin' is the wordplay.
'oddball' indicates an anagram (I've seen this in other clues).
'with' says to put letters next to each other.
'seen' put after 'colin' is 'colinseen'.
'colinseen' is an anagram of 'INSOLENCE'.
'from' is the link.
(Other definitions for insolence that I've seen before include "lack of respect" , "Lip; cheek" , "Hubris" , "Rude disrespect" , "Rudeness, impudence" .)
