This is basically someone that you know will say go with you to prom if you ask them. This has to be a person that you can relatively stand for a full night, or else can stand to stand next while taking pictures and then ditch him/her for the rest of the night and hang out with that person that you actually wanted to come with. This has to be a person that you know no one else will want to ask, so they are definately available.
Steve is my back-up, back-up prom date, so I know that I am guaranteed to be going with someone.
