jackaler
A useless, lazy student who thinks they're cool just because they talk too much and don't do anything. They live in the library during finals, the dining hall when it's time to eat, and sleep in their messy dorms the rest of the time. They don't care about anyone else and leave a huge mess everywhere they go.
My roommate is a jackaler. He eats cereal for dinner and leaves a trail of crumbs from the dorm to the library.
I saw a jackaler wearing a hat inside the library. He didn’t even take it off.
The jackaler next to me snored so loud I could hear him from the other side of the room.
