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

Group Greekage

When a large group of Ancient Greek soldiers (sometimes related) have an incredibly massive gay orgy during funeral games

Antaeus- “I can’t believe General Marnes is dead”
Phileas- “I know, right? Now get everyone together for a Group Greekage and we’ll all have some dope gay sex”
