Get the 5 litremug. when you're doing something you're not supposed to be doing and someone yells 5'0 that means they're giving you a warning because you're going to get caught
say you're looking through the teachers drawer and your friend is on the look out and see's your teacher coming, he/she will yell 5'O so you can be warned and pretend like you're innocent
