Pronoun Dressing Room is a gem I found from Kylie Brook's Polyamory group thread. Maybe it's not a lolcow but it's a pretty similar kind of fun stupidity to the Genderbread world creator. Here the aim is to make up new pronouns, and the site inserts them into famous works of literature like Alice in Wonderland so you can see if they flow correctly. They helpfully have premade categories like "Astronomical" and "Avian". The classic works of literature also have trigger warnings in case you happen to be triggered by "Mention of food" or "Mention of unnamed sister." Why not give it a try?
