Arroz con Culo
Puerto Rican expression meaning a huge mess or mixup.
Literally, it means, rice with ass. So naturally, since Puerto Ricans love rice, adding ass would really mess things up.
Muchacho, cuando ella lo pillo mirando la culona, se formo un arroz con culo.
Dude, when she caught him staring at that chick with the big ass, the situation became a huge mess.
