Depends. If you specifically have trauma from being called dipshit then it doesn't.

🍔 is the set of integers modulo 2 (more literally, if two integers differ by an even integer you consider them the same). I can write out more in a bit.

Edit: this previous post has some good comments, and you can find some of the notation and the answer on the wikipedia page for cohomology ring (they use F~2~ for integers mod 2 and RP^n^ instead of P^n^(R)). I don't know enough algebraic topology to actually know why that's the answer but I can at least answer these:

The first definition of 🍕 with the contravariant thing also doesn’t parse for me, what does that “-” mean in the function arguments?

I assume it's shorthand for saying that if you define f(x) = 🍕(x, B) then f : C --> Set is contravariant.

In the definition of 🌭, what is the n (or the P)? ChatGPT started yapping about real projective space, but I’m not sure if that’s correct.

It's not the notation I'm used to (I'd also think of power sets first), but I think it's n-dimensional real projective space.

and Paris made a lot of progress in getting rid of cars since then

I don't think this is a political compass

There's lots of fish species in danger of going extinct

You know, I don't think I've ever heard that song in full. Apparently the dogs are metaphorical

The original is iPad/iPod/iPaid, then someone added iPeed to the dog (and farded and shidded and camed), then comes this version that changes iPeed to something completely unrelated

This is probably a me thing, but if I were to catch on to someone doing this I might start wondering at some hidden intent behind everything they do

That's just the rule of Tumblr screenshots, you always have to include one reply too many

Oh yeah I know KenM, I meant the second part. You could get the same kind of responses on Lemmy

It's strange, because Ripley is like the #1 "I don't hate women in movies, just bad writing" excuse

Didn't Jack Dorsey leave Bluesky?
