A Dutch oven is a big pot that you can put on top of a stove and do things like boil pasta, at least that's what I use mine for. And I have no idea why it would be worth negative ten points, in my book it would be worth something positive.

Hehe, I love ours at home. We always make our St. Patrick's Day dinner in it, and it's delicious!

"Dutch oven" is also a slang term for the following prank:

If you are sharing a bed or snuggling on a couch with someone under a blanket, you fart (under the blanket) and pull the blanket over the other person's head so they're trapped with the smell.

I've never been involved in such a prank, but I have heard of it.

What exactly is a meme? I've seen them on a few LJ's that I read.
