Ok, in the TV series Glee season3 episode 21, I came across this sentence: you were a smash. From the context, it might mean you were wonderful or something. Then I looked this up online, I found smash means sex in Urban Dictonary, which is definitely not what I was looking for. So is there a phrase you are a smash? What does it mean?
well, then I found this smash, slang, which says that smash can mean a successful thing, especially a movie, so can you use it to describe people?
