Hey Wójcik :D So, I'll try to explain to you what some of those expressions mean, but actually I never heard about the first one. 2. fazer falta - that expression can has more than one meaning. If you're talking about some sport, It means fault, but it can be used when you're missing someone. Ex: "Ele está fazendo falta" (I'm missing him). 3. correr o risco - It can has more than one meaning too. If you put it on the sentence "Vou correr o risco", It means you'll take your chances, even if something can go wrong. Else, if you say that someone or something is "Correndo o risco", It means that something can go wrong, so there are risks. 4. comer as horas - I think this can be used when the time is running to fast. Sorry for my bad English, and I hope I've helped you! If you have any questions, hit me up and I'll try to help. XD

Aí você diz isso para a pessoa que vai se mudar.

1. leave behind, forget (never heard anybody saying that though). 2. to miss somebody or something. (voce me faz falta = i miss you). (faz falta ter alguem para conversar = I miss having somebody to talk to) 3. passively take a risk. (se voce nao trabalhar, corre o risco de ficar sem dinheiro = if you dont work, you might as well end up with no money). 4. that literally means "eating for hours" but if thats a slang as well, i have no idea.

Fazer falta, exemplo: Quando alguém vai se mudar ( da cidade dele/dela, por exemplo) e você vai sentir saudade dessa pessoa, aí você diz: você vai fazer falta. Fazer falta, example: When someone is going to move (from his/her city to another, for example) and you will miss this person, then you say: você vai fazer falta.
