Someone who thinks that you can just go to sleep, but it's not that easy, they will never understand. They tell you just to go to sleep instead of staying up all night when you tell them your tired. They say it's your fault your tired, but it's not.
Person 1: I couldn't sleep last night
Person 2: Then you should've gotten off your phone and went to sleep.
Person 1: Fuck you it's not that easy stop being sleepist. Stop rubbing your sleep privilege in my face.
A sleepist is someone who judges you by the way you sleep or what time you go to sleep
Man: I go to sleep at 4 in the morning
Man 2: wtf who does that
Man: stop being a sleepist
Someone who is offensive towards people go actually sleep instead of staying up all night.
