Junk guides picked up (4)

Ross

I believe the answer is:

spam

'junk' is the definition.
(I've seen this before)

'guides picked up' is the wordplay.
'guides' becomes 'maps' (a map is a guide to a place).
'picked up' says the letters should be written backwards.
'maps' backwards is 'SPAM'.

(Other definitions for spam that I've seen before include "Send unsolicited mail" , "Spiced ham" , "Uninvited email" , "unsolicited communication" , "Thoughtlessly send" .)

I've seen this clue in The Times.
