Preemptive unfriending 

When one deletes a friend from Facebook because he or she knows that the Facebook friend in question would eventually delete them instead. Preemptive unfriending thus robs the deleted Facebook friend of the joy of being able to delete them.

John: Why'd you delete Bec from you friend list?
Adam: I knew she'd eventually delete me so I wanted to take the satisfaction of unfriending for myself.
John: Ah, a preemptive unfriending.

Pending Unfriending 

When someone you're friends with on a social network takes too much of an interest in their profile (generates an excessive amount of posts) or in your profile (generates an excessive amount of comments on your profile), and you contemplate terminating the "friend" status.

Contemplation can also be due to terminated relationships, etc.

Girl 1: Oh my God... Becky is so annoying on Facebook. She comments on like, ALL of my pictures.

Girl 2: I know, right! Right now she's Pending Unfriending.
