The act of going on Facebook and untagging yourself from incriminating photos. Whether it be cause your parents are getting a Facebook or you just don't want people to see you in embarrassing pictures from last night.
You: "Wow mom is getting a Facebook"
Friend: "Haha, Dude that sucks, you have so many messed up pictures"
You: "Tell me about it, I'm gonna have to go on an untagging spree"
