"Stick around!" (4)
I believe the answer is:
stay
'stick around' is the definition.
(I know that stick around can be written as stay)
This is the entire clue.
(Other definitions for stay that I've seen before include "Visit (for the night)" , "Rope or wire used to support a mast" , "Remain; brace" , "Stick around" , "Thin strip used to stiffen a garment" .)
