what does "topper" even mean?

The title 🥺

I feel the term is very subjective and varies from person to person. For someone, it could be a person who scores 95%+ and for someone else, it could be someone who has bagged maybe 99.99%.

For a third person, perhaps, it could be actually understanding and using the stuff you learn in real life.

Wtf does the term "TOPPER" mean according to y'all?
