I once heard a cutting assessment of someone’s intellect in Argentinian Spanish that went jugas al tetris y giras el cuadradito. It means “you spin the square tile on Tetris.”

There’s a great expression from Argentinian Spanish about someone who’s sticking their oar in that goes vos no te peinés que no salís en esta foto. It means “don’t comb your hair because you don’t appear in this photograph.”
