From now on...
1. Dan and I were talking about if you could have sex with someone but be really quiet so they didn't know. I volunteered the term "Sex Ninja" for this, Dan voluteered the term "rapist". We laughed out loud at our mutual joke. From now on all rapists will be known as Sex Ninjas.
2. I mentioned to Dan that something would be "unuseful". We agreed this wasn't a real word - the correct version is "not useful". Even though it wasn't a real word, it was clear that "unuseful" was understood in context. When Dan proposed that "unuseful" is the reciprocal of "useful", I demanded that from now on we no longer use negatives, but state that something's negative is the reciprocal of the aforementioned something. For example: "Dan Brown's writing is the reciprocal of brilliance.".
3. I just managed to write the sentence: "In particle physics accelerators are used to accelerate particles." This isn't a from now on thing but it is still an absolutely ridiculous sentence.
Dan finishes work soon. Then dinner. Hooray.
P.S. The only time you shouldn't use the reciprocal thing is when stating that there is no more of something. It is still correct to say "Nimogen". Although why you would ever say that is beyond me.
