How Do You Say 'That Sucks' in Spanish Or something to that effect. Muchas Gracias :-)

What Does 'Vale' Mean and How Is It Used. I though that 'vale' only means 'ok' in spain, but a friend of mine told me there's more to it. It can also be used to indicate 'no', but his explanation was not very clear. What are the other ways to use 'vale'? !Muchas Gracias!

What Does 'lo que' Mean and How Is It Used? I've looked in the dictionary, and it says that 'lo que' means whatever or whichever. However, I encountered some phrases like 'No todo lo que brilla es oro' and the definition doesn't make sense anymore. How to use 'lo que' in a sentence and how is it difeerent from 'que'? Help, anyone? Thanks in advance. !Muchas gracias!
