The group of three (or possibly more, you never really can tell) who get back from a night out at 3am and enter/exit the room about 445 times, slamming the door on the way in and out every single time, before actually sleeping. They sleep for three hours then start it all back up at 6am and finally leave an hour later.

If it’s a female only dorm, these are the same girls who drop by the room 2-4 times throughout the day and night to change and reapply copious amounts of perfume and aerosol deodorant, usually in dorm room where the windows cannot be opened and everyone else is left to suffocate while they attempt to squeeze in an extra hour of sleep now that they’re gone.
