1. The red string of fate. Also known as the Red thread of destiny. It is the invisible red string that supposedly connects two people together. Similar to the idea of soul mates. It is said that the red string may stretch or tangle but can never break.

2. An extremely awesome webcomic by Gina Biggs about the red sting of fate.

Those toys that you become obsessed with when you're in grade school because you think they're magic. Later in life they are known to be great nooses.

The pull cord on jabberboxes, conversationalists, and airbarkers that starts em ranting until the cord is gone ( or you pull it again).

When words are strung together in such a way as to make what is being conveyed by the writer or the speaker intensely powerful, even unforgettable.

An worm on an string is an worm your friend gives you. You get emotionally attached to it in 0.5 seconds then within 4 hours of owning it someone steels it. You make an sign with an picture of the worm and post it online with an reward of $5.

Having only sex with someone and nothing else but that. No hanging out unless it’s to fuck

Quite possibly the wierdest physics theory ever. While all of the math behind it is correct, attempting to understand it is like having molten platnium poured on your skull. The theory is something like this:
1. Everything is made of molecules (duh).
2. Molecules are made of atoms (also duh).
3. Atoms are made of electrons, protons, and neutrons (very duh).
4. Electrons, protons, and neutrons can be split in half to create quarks.
5. Quarks are actually made of even smaller pieces, called strings.
Strings are eleven-dimensional (ten dimensions + time) bits of energy that not only make up the above particles but create forces including gravity, electromagnetism, strong nuclear forces, weak nuclear forces, and a few other forces that have not yet been discovered.
Strings are so infitismally small that anyone with an IQ of less that 400 (ie, all humans) is incapable of imagining how small they are. To give you an example, imagine an atom of hydrogen was the size of the solar system. On the same scale, a single string would be the size of small tree.
String theory also includes a bunch of theorys including m-theory, relativity, chaos theory, and a few others that may or may not have been invented by someone who was on LSD at the time (if you've ever seen any Mandelbrot Fractals, you'll know what I mean).
