Sat around in New York being abusive (5)
I believe the answer is:
nasty
'abusive' is the definition.
(thesaurus)
'sat around in new york' is the wordplay.
'around' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'new york' becomes 'ny'.
'sat' is an anagram of 'ast'.
'ast' placed into 'ny' is 'NASTY'.
'being' acts as a link.
(Other definitions for nasty that I've seen before include "Foul" , "Repulsive" , "Offensive or malicious" , "Filthy" , "Obscene" .)
