The "Materwelon" meme is a brilliant botanical bamboozle! It shows a watermelon with its colors inverted—red on the outside, green on the inside—creating a fictional fruit called "materwelon." The phrase "GET MATERWELONED" is the scientific equivalent of getting rickrolled, but with fruit genetics. Watermelons naturally contain citrulline (hence the title's D-citrulline reference), but this color-inverted monstrosity would require some serious CRISPR engineering. It's the kind of genetic prank that would make Gregor Mendel spit out his pea soup. Next time your biology professor asks about phenotypic expression, just submit this as your final answer.
