[Image description: text which says "You're a 10 but it's on the pH scale". Underneath is a picture of a woman whose face suggests she is dropping hard truths. OP has since learned that this is a character from a show saying "You're basic" and that the post is accidentally self-referential]
This character is saying one of her catchphrases here: "Ya basic". The Good Place, S1E13
I try to make my alt text include the source media if i can, but i don't think it necessarily ruins the joke of the post just bc the alt text doesn't say, "This is the character Eleanor Shellstrop from the show The Good Place"
Fwiw I laughed at the pH joke without any concept of who that person is, so I agree with you
exactly my point!
