ELI5: Explain Like I'm 5

Benny (slang)

Okay kiddo, benny is a word people use as slang for a type of medicine that helps them stay awake and alert. This medicine is called amphetamine or sometimes methamphetamine, which are really big words that mean it can help people focus better and stay up longer. But you should know that taking medicine without a doctor's permission is not safe or healthy, and it can cause a lot of problems. So remember, don't use words like benny or try to take medicine without permission from an adult you trust, like a parent or a doctor.
