You've never been to karaoke before? We'll definately have to go sometime it's a lot of fun. What you do is you or a friend pick out a song that you like and sing while the music plays and words come up on a screen just in case you don't know the lyrics. Though some people also do black box karaoke where they randomly pick a song and sing whatever comes up.
I was hoping that they would have a karaoke bar here but since there isn't I've been working on at least getting a machine in the arcade or bar for people to use.
