After socializing for 5 hours I was absolutely zonked, so I had to take a long nap.
When someone has instantly passed out while sitting or laying down
Guy A: "Damn, Guy B just Zonked as soon as he closed his eyes"
When you take to many edibles,or smoke too much shader. And forget several hours at a time.
Man I was totally zonked today.
ZONKED (Adjective): Zonked is often used by 90’s babies to describe how high their intoxication level is. Just like any other drug related slang it usually is used primarily for a single substance or multiple. In this case Zonked would is most commonly used for Xanax or similar prescription pills and secondly marijuana (but not as often).
“Wow man, I just took a little bit of that Xanax bar and I am absolutely ZONKED”
