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.
