How do I make the "Spoiler Text?"

[goat mom]

I'm trying to make a new discussion and what I'm saying has spoilers in it, and I want to use that Spoiler Text thing, but I don't know how. I've already looked at the "Formatting help" thing, but I don't understand how to make my text covered. Please help!
