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.
Kad se šef izviče na vas ili profesor napravi budalu od vas pred svima, kad se ozbiljno posvađate s prijateljem i danima ne možete  prestati razmišljati o tome, nekada čak i tjednima.
