Bennie

Someone who assigns alot of homework. A professor in nature, someone who would assign a 5 minute quiz. A guy who won't tolerate an open laptop during his lectures. Somebody who teaches for fun and enjoys ruining the education system.

Our teacher has been a real Bennie this semester with all of the essays and emails, how are we supposed to pass?

Benny’s

A slang term for Benadryl. Benny’s can be easily abused, especially the pink and blue ones. The clear ones smack too! They’re used for histamine when you have a allergic reaction and work the the best. Also used for sleep aid. So let’s say you pop one and you dodge the sleep, booooy you are high

Maaaaaaane I’m feelin delusional off these benny’s
