They may have a crush on you (4)
I believe the answer is:
boas
'they may have a crush on you' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for boas that I've seen before include "Large snakes" , "Long fluffy scarves of feathers" , "21 [SNAKES]" , "Cold-blooded creatures" .)
