The best at everything

The person in your classes who just doesn’t get anything wrong! You try your best to be like them, but sometimes you get caught cheating on the test. The best at everything is usually a snitch.

Eg:

You accidentally drop your pencil, go to pick it up and look at someone’s work because you can.
Me: Oops, I dropped my pencil.
The best at everything: Sir! She’s tryna copy me!
Sir: Detention!!!!
