This is when a bunch of nasty lawn gnomes get together and congregate on when they are going to take over the world. When they meet they usually wear very funny hats (i mean really funny). its kind of like a klan meeting except the gnomes are very peaceful and not racist and take to the liking of fish paste.
yo son i saw the oodenblatt meeting the other day.
oh word? yeah we should totally join except i dont like fish all that much.
