Silent Disco

This term was originally used to name an event in which a group of people all rock out to the same song playing on headphones. However, onlookers cannot hear the song in the headphones and therefore, the group looks ridiculous. While participating in a silent disco, if you turn off/take off your headphones, you can hear everyone messing up the words to that particular song. Therefore, this phrase NOW refers to someone completely messing up the words to a song, but are convinced that they know them, and therefore, persevere.

Rick: "Shit, you totally just Silent Disco-ed that song."

Silent Friend

Well, this is a term I came up with meaning if someone joins your MySpace page or whatever social network you use and they just join and not say anything at all to you but yet they want to be your friend.
Makes no kind of sense!

You get a in this case, a MySpace friend request and you add that person and they don't say anything to you at all. That's a Silent Friend.
