It's a meme about kids looking older when they're younger. Party of it it actually that girls are going into puberty at earlier ages. And there's a meme about girls that are way too developed way too early because of earlier puberty rates. It became a more popular meme after Danielle Bregoli became a meme because she's like 13 but way too developed for her age.
