I recently submitted a definition of "rationalussy" to Urban Dictionary to make this market resolve YES: /astyerche/will-someone-provide-a-definition-o .
I used @StevenK's definition from /MartinRandall/what-is-the-best-definition-of-rati . The definition was just accepted (https://www.urbandictionary.com/define.php?term=Rationalussy), which means it is now possible to buy a "Rationalussy" mug from Urban Dictionary. If anybody buys the mug and gives me proof that they now own it (such as photographic evidence in the comments), I will resolve this market YES. It doesn't have to use Steven's definition - if there is another definition of "rationalussy" on Urban Dictionary at the time, a mug with that definition also works.
If I get no evidence that this has happened before the closure date, I will resolve this to NO.
@jfjurchen Well, there are four other definitions from the other market. I didn't use the one chosen by the market because I thought it was kind of boring, but I might submit Isaac King's definition as well, since that one was also pretty funny. I only submitted one originally because I didn't want Urban Dictionary to get confused that there were two totally different definitions of the word and reject it on that basis.
And of course, if you don't like any of those definitions, you can come up with your own and submit it.
