face purging
You throw out the useless, weird, and completely random people who somehow ended up on your Facebook friends list. They never talked to you. They just saw a picture and clicked accept.
I purged my Facebook friends list because I was tired of seeing my cousin's cat's butt 24/7.
That guy who added me because he thought I was a girl? He's gone. Forever.
I had 300 friends. Now I have 3. The rest are trash.
