What does the internet slang "草生えた" mean?


I came across the term 草生えた on the internet. There wasn't much context, but it
didn't seem to mean that grass was growing. Is this a slang term?

What does it mean? I couldn't find it in any of my dictionaries.




Thanks to @Chocolate, I was able to learn what this word means, which is
roughly that something was funny. Here are a couple sources:

  1. <http://wikiwiki.jp/himoteplus/?%C1%F0%C0%B8%A4%A8%A4%BF>
  2. <http://www.logsoku.com/r/livejupiter/1340676537/>

Why does it mean something was funny? Well, as discussed in [this
question](https://japanese.stackexchange.com/questions/143/what-is-the-
meaning-of-all-those-ws-in-email-and-snss/145#145), strings of `w` (such as
`wwwwww`) express laughter, like the English term "LOL". At some point,
someone must have decided `wwww` looked like little blades of grass, so they
came up with the expression `草生えた` ("grew grass") to indirectly express the
same thing.
