Number 10, the nuts juice
Everyone was asking if various liquids were "nuts juice". Yeah, that one was kinda gross.
Number 11, Oats
Oats. Just the word "Oats" absolutely EVERYWHERE.
And here it is! There is probably a lot I miss but those ones are the main ones.
Now that I think about it, it's been quite some times since the latest big mastomeme 🤔.
@Sylvhem i think my favourite meme was https://octodon.social/users/Siphonay/statuses/99540922848626578
(probably because i was actually around at the time)
@Sylvhem I think at some point it mutated from "animals captioned with a" to "any picture captioned with b"
@magical Oh I didn't know that one! Thanks.
