class buddy

The person you sit next to in a certain class, but never hang out with or talk to outside of that class. Usually only needed because your friends aren't in that class, or because your teacher assigned you seats.

In common usage, the word 'class' is replaced with the class you're referring to, e.g. French, English, Maths.

1. How do you even know that guy?

He's my Math buddy. We work on fractions together.

2. She wasn't my friend, she was my French buddy. Working on irregular verbs does not count as a friendship.

3. He was my class buddy. Not sure what class.
