Draking is the act of leaving somebody on delivered for a while in a public messaging chat, typically Discord, and then responding a long time later, when you forgot the initial conversation.
Person 1: Hey how’s it going?
(Waits 2 hours)
Person 2: It’s going great, hru?
Person 1: Dude was draking me 💀
Meaning: Getting yourself so high/drunk that you are unable to perform at your own concert.
Guy: Did you hear about that cancelled concert?
Friend: Yeah, that artist totally draked out!
Guy: Why is he in the coffeeshop? He has to do a concert in a few hours.
Friend: For real! He's draking again isn't he?
