the creepy people who hang around at boarding schools/colleges when they have a perfectly good house of their own to go to, yet insist on spending all of their time at school mooching off of boarders.
of a lower class than boarding students.
Jill: Who's that girl who's always in your room?
Mary: Oh, no one. She's a day student, she eats my food then leaves at night.

A completely misunderstood and secluded group of students at a boarding school. There are less day students than boarders at most schools, so it's common knowledge that it's harder to get into good boarding schools as a day student.

in comparison with their sworn enemies, the boarders, day students are more civilized. It is a proven fact that they have higher grade point averages as well. Plus, they get to go home every day and do whatever they want without curfews and without having to pay a cab to take them everywhere. Most have their licenses, so they can come and go as they please. This makes the boarders insane with jealousy, causing them to hate on the day students.

It is because of this jealousy that the day students are extremely secluded from the rest of the student body and are often referred to as sketchy when in fact most are not sketchy at all.
First Day of School at DA:
Boarder: "Hey, I'm from Greenwich. Where are you from?"
Day Student: "I'm from Greenfield..."
Boarder:"Hahaha. Get the hell away from me, loser."

1) A student at a boarding school who's too pussy to sleep there; one who participates in homosexual activity.

2) A student at a boarding school who has no friends; thinks they're cooler than they are. This student usually tries to hangs out with boarding students older than them (that don't like them).
Boarding Student: "Why aren't you sleeping over tonight ?"
Day Stud: "Because I'm day student-ing it up tonight with my dad. Wanna join?"
