Almost clever advertizing

Ok so you go to university to get an education and to voice your opinions. And in doing this you explore all types of clubs and meet many different people. And these functions advertize. I understand that you need a catchy ad to get people involved. But is there really a need for putting acronyms all over the place that no one knows. And then its another thing that is really annoying when people go an deface these things because they are ignorant. Arg!
