A nickname for a hot room that smells like burnt toast and regret. It’s basically a sauna for people who hate life.

I walked into the H-box and it felt like I was in a microwave.

My friend’s H-box was so hot he had to wear a hat inside it.

The H-box at school is where people go to cry and forget their problems.
