Years ago when I got asked to join staff on X-Men Movieverse MOO, I took the staff bit name Rosalind. (It was a Shakespearean theme.) Which shortened to Roz, which has become my regular online alias.
For some reason, I sometimes have issues getting jokes in online chat. (Not in the 'ugh you have no sense of humor, learn how to take a joke,' although I'm sure some people who have tried to tell gross jokes in front of me might say that, but in the 'I don't get it???' kind of way and then everyone laughs at me.) It became such a running joke on XMM that my name became a verb for not getting a joke. "You rozzed the joke!" (Which is now the top result on Urban Dictionary.) Which is why I show up in some other spaces as rozzingit if Roz is already taken. Which I realized halfway through this is not actually the case here, where I'm just Roz, but I'm not deleting my story so there.
