(Adjective) Usually caused by drug use, it’s when you’re not sleepwalking but not fully awake either. You’re awake, but you’re acting as if you had no agency and things only happen to you. But also you’re not like a zombie.
1. To fall asleep, normally because of exhaustion.
2. The original term 'zonked' was coined by Ken Kesey and his band of Merry Pranksters. It originally meant that you were high on LSD. Nowadays, it just refers to being stupendously stoned, on any drug.
