Thoomsday

Technically a holiday comprising of 2 days, those being August 2nd and 3rd, it is a day of celebration amongst the men of my group chat

Elan: When we hanging out?
Hector: Thoomsday
Elan: *Makes definition of Thoomsday*
Hector: Did you really do all of this for a meme?
Elan: You can bet your fucking ass I did
