I'm a little stuck... Click here to teach me more about this clue!

'hang around' is the definition.

I don't understand the rest of the clue.

(Other definitions for loiter that I've seen before include "Linger, with intent perhaps" , "Linger - lurk" , "Skulk" , "Hang around, perhaps with intent" , "Hang about, with 25 dn perhaps" .)

I've seen this clue in The Times.
