Fuck You Friend Request 

this can be defined as people who have asked to befriend you on a social website like Facebook, Myspace, etc. that you keep there either because you dont particularly like the person or for your own personal amusement or any other reason that pretty much means your not going to accept the request but let them think you will.

That chick i used to like asked me to accept her friend request, she'll be on my "Fuck You Friend Request" page for a long time.
-------------or-------------
