a 3rd grade
When you and two friends fight over the same boy on a rock during recess and you call him 3rd grade whenever you talk about him like he’s a piece of trash.
During recess, I fought over the same boy on a rock and now I call him 3rd grade every time I see him.
At lunch, my friend said, 'He’s 3rd grade because he’s a piece of trash and we all know it.'
We fought over the same boy on the rock, and now he’s 3rd grade forever.
