Taken from literary sources, including the 'weird sisters' of Macbeth, a weirdsis has remarkable (almost witch-like) intuition and the ability to talk in rhyme!
Person: "What you said was going to happen just did. That's spooky. You're such a weirdsis."
A weirdsis: "My instincts speak like I have a cauldron in my gut; they're sharp, and rarely wrong, but can be a pain in the butt."
