When a someone expects special discount or other benefits above and beyond the ordinary from a service provider because of a friendly relationship, but then also expects all the benefits of a traditional customer/business transaction.
You give a neighbor or friend the discount over what you'd normally charge, and come over on the weekend, then they are confriending you by expectingall the same level of service you'd give a full paying client.
The act of neither confirming nor ignoring a facebook friend request, thereby leaving the friend request that is "awaiting confirmation" hovering in your friend request box indefinitely, leaving the requester completely powerless.
Janie: Hey, did you ever respond to that friend request from Kathleen?
Elena: No way! I totally nonfriended her. She can keep waiting.
Janie: Nonfriending is the only way to go with that crazy bitch. You wouldn't want her to facestalk you anyways.
