Character of bad boys having some money's low (6)
I believe the answer is:
symbol
'character' is the definition.
(I've seen this before)
'bad boys having some money's low' is the wordplay.
'bad' indicates anagramming the letters.
'having' means one lot of letters go next to another.
'some' says to take the initial letters.
The initial letters of 'moneys low' is 'ml'.
'boys'+'ml'='boysml'
'boysml' is an anagram of 'SYMBOL'.
'of' is the link.
(Other definitions for symbol that I've seen before include "My lobs (anag)" , "Emblem or sign" , "Sign - representation" , "Meaningful character" , "Something that stands for or suggests another thing" .)
