Slacker address (4)
I believe the answer is:
dude
'slacker address' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dude that I've seen before include "A (dandy) American city dweller" , "He's no cowboy" , "Man (US colloq.)" , "Dandy - US or Canadian city dweller" , "Level" .)
