Guy to stick around (4)
I believe the answer is:
stay
I believe this clue is a double definition.
'guy' is the first definition.
(both can mean a rope)
'to stick around' is the second definition.
('stay' can be a synonym of 'stick around')
(Other definitions for stay that I've seen before include "Thin strip used to stiffen a garment" , "Period in one place" , "Rope bracing a mast etc" , "Remain; detain" , "Visit (for the night)" .)
