It's when your boss yells at you or your professor makes you feel stupid in class, or you have big fight with a friend and you just can't stop replaying the scene in your head for days, sometimes for weeks on end.
É cando o xefe che berra, ou o profesor  te fai sentir estúpido na clase, ou tes unha gran rifa cun amigo, e non podes deixar de reproducir a escena na cabeza durante días, ás veces semanas, sen parar.
