Didn't invent it, but did get so weirdly intense about it for a few days that it's now permanently part of the site culture. I think there were a few other struggle sessions at the time and people were at each others throats about anything.

Plus, I think it gets used as a safe way to refer to early days struggle sessions. Some of the other topics could kick off drama just from being brought up, but nobody's (probably) going to do that over outdoor cats.
