Senzu bean 

slang for Adderal, Vyvanse, or other ADD meds used to quickly restore ones energy. Frequently used to pull all-nighters, or to recover from a night of legendary shenanigans.

We were out until 5 AM last night then remembered about our math exam in 4 hours so we all popped some Senzu beans and were ready to go
