Job Application means in slang: A blank piece of paper, usually with a cut hole in the middle. This implies that the application is portable and the candidate will need to do sexual favors in order to be hired. It refers to applying for work at a club. It can also be used to insult someone by telling them to lose it or to tell you that they don’t care about what you want. (in Slang Dictionary, added by Leocadia Gutiérrez)
