ok that sounds so stupid but what is the meaning of spoiler ???

I think it referres to information that is reaveled about an Anime or a Character etc that other people watching the show may not yet know. Some people don't want to know what happens, befor they get to see it for themselves, because it can Spoil the surprise. that is why it is called a Spoiler:)

Hope this answer helped:)

A "spoiler" is information that may "spoil" a book, show, or movie for someone. For example if someone wrote "I can't believe _________ died at the end of ________!" That would be a spoiler.

basically it just spoils plot points. like, if you haven't already gotten far enough into a series or something and it could give something away.

Sometimes with such questions
I wonder why someone don't search in google
when he something don't know...
I just tick and knows everything
Google, don't bite!
Are people are so lazy that they must ask for something other?
I will understood if it were something difficult to find, but this?
Other questions that are really hard to find the answer are lost in question like this one...
