Crowley would definitely take advantage of modern day shitpost style memes in order to vent his existential Angst TM while still passing it off as a joke. He’d post shit like a picture of one of his plants captioned “the universe has an inevitable end” in comic sans, then there’s another one in a shitty jpeg blurry plant closeup, captioned “morality is relative and nothing is correct”.
It just starts off when he’s drunk and starts doing it because funny but then it turns into a meme and Aziraphale thinks its some ploy to corrupt the youth of today but no. Crowley is just in a constant existential crisis. He turned his uncertainty of his placement of the universe into a meme and on one hand it’s TECHNICALLY corruption but on the other hand goddammit now his existential crisis is a running gag on the internet so what the fuck.
