wrong request
When you send a friend request to the wrong person on Facebook because they have the same name as the person you wanted to friend. Can end awkwardly or you can cancel it before they find out.
(in a Facebook message)

John: Hey, why did you friend me? Do I know you?

Marie: Oh sorry, wrong request. I wanted to friend John Parker. I guess you are not the one I know. Haha lol hv a good day.
