Hi Tevo, "Big time" is simply used to emphasize what comes before. They could have said: "It was sooooooooooo nice to meet you!" Another example is: "I failed big time", i.e. I failed by a wide margin! Hope this helps.

when you have the best and most successful level in your profession or business, u mention it as the big time. ;) and it refers to sth in the past.

You are an important and wealthy person. It is often a joke. Not to mean. Just sarcasm. This is what big time usually means. Yet it can sometimes be a fun event that someone put together with much care and work. We had a big time.

This expression is often used in sports and show business. "After winning awards with the independent film, the director moved to Hollywood, which was followed by big time success." You can also say, "I'm so sorry. I know I messed up big time." It's saying that not only did you mess up, you REALLY messed up.

Pretty helpful, thanks everyone! Just another thing about it, is this more used in Canada or it's used in any english-speaking country?
