i see a lot of commenters thinking this is a bot meme. so, i'm gonna explain the joke in excruciatingly painful detail for the normies, who i hope are never required to "get" this meme otherwise.

in hospitals, people sometimes decorate the floor with various liquids, sometimes willingly.
as a cleaner, you need to be able to dump a bucket of bleach on this hospital floor, and get scrubbing quickly.
to facilitate this, the floors are made out of a smooth material with minimal pores. you dump bleach, and it just works.
this comes with a side effect of the floor needing to be very, very slippy.

psych ward patients must have all their gear removed, this includes shoes and socks.
this is because you can use the laces and elastic to commit sudoku.
but now all your psych patients are at high risk of slips and falls instead.
to counter this, "hospital grip socks" are issued, like the yellow socks in the bottom left of OP's meme.
these are issued to patients as part of their hospital uniform, to counter the slippy floor problem.
you can now navigate your room safely without slipping and injuring yourself.
these socks are also issued to regular patients like elderly, weak to stand, etc etc. but on the internet, these are "psych ward socks"
~
so, the actual joke is that OP is outing themself as a psych patient by demonstrating knowledge of the uniform.
sidenote: i assume the orange sandals are for bougie in-patients at private facilities? it seems silly tbh, i would want to throw them.
