Clue: [Creep lazes about, say, around bar endlessly] (9)
Answer: SLEAZEBAG
Explanation: Definition: Creep
A charade of SLEAZ, an anagram ('about') of 'lazes' plus EBAG, an envelope ('around') of 'ba[r]' minus the last letter ('endlessly') in EG ('say'). The square brackets in the clue serve no discernible purpose – unless perhaps it was the intention to replace the clue or answer, and it never happened.
