Get the defriend mug.
The act of deleting someone on an online socializing site like Facebook or Myspace.

This usually happens when someone you don't know requests to be your friend so you accept them to see their profile. Once you realize that you don't know them or that they are a complete creeper, you attempt to 'defriend' them. This usually proves to be a nuisance and a pain to figure out how to do.
Person 1: I'm going on this trip to France and a guy from another school friended me, I messaged him 'cause I wasn't sure who he was, and he gave me a total creeper response.

Person 2: Man, defriend that fool.

A large-scale deletion of friends from a social networking site. Similar to deforestation, it can have drastic effects on the remaining landscape of your friends list. The people you unfriend may then Facebook chat rape or Facebook stalk your mutual friends, asking why you've cleared an entire forest of people.

I had to defriend this dude I thought I knew from my high school days, but it turned out I didn't. He was sending me all sorts of events spam!
