this feeling occurs in any situation where you feels as if you have been cheated on friend wise.
ex.
when earlakeisha came to find out that her friends aquafina and shawnda had become close friends without her knowledge, she couln't help but feel really offriended.
When someone receives a friend request from someone they don't know, and is so conceited and unfriendly that they report the person instead of merely ignoring the request.
"I got this friend request today from some guy, I have no idea who he is! I mean seriously, can't he see I'm better than him? I'm so afriended!"
