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.

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.

I had a trucker's tan after driving for 10 straight hours on a sunny day.
