You will hear more stupid nicknames than you ever thought possible. Phone calls almost never happen and when they do, you just don't get the messages. Cereal makes a meal any time of day. ATMs are the devil's advocate. You almost forget how to drive.
People still cheat, it's just more technologically advanced.
You get really good with excuses for skipping class. The girl you're going to marry may live right next door, so keep your stereo down. Ordering food at 1 am is a common occurance. You never realized how cool you can be. TV becomes a bigger time sucker than ever before.
