National Unus Annus Day

Definition

An unofficial November 14th commemoration of the YouTube channel Unus Annus, which Markiplier and CrankGamePlays deliberately deleted after exactly one year to make a point about mortality and impermanence. Fans celebrate by wearing black and white or channel merch, essentially throwing a birthday party for something that's dead. It's philosophy meets internet culture in the most Gen Z way possible.

Example Usage

I'm wearing all black tomorrow for National Unus Annus Day—memento mori and all that.

yawntastic

A delightfully sarcastic portmanteau combining 'yawn' and 'fantastic' to describe something spectacularly boring. It's the perfect passive-aggressive descriptor for that three-hour presentation about quarterly metrics or your friend's vacation slideshow. Because sometimes 'boring' just doesn't capture the sheer magnitude of tedium.
