We need a 'horriformative' reaction for posts like that, gross and enlightening at the same time.
Oh, man... see, I often take for granted that people know a shitload about furries, and about internet nerds in general, but some of this lore goes
way back decades ago, and may be blessedly new to a lot of folks. Slight PL, but
I'm getting towards Lou's age, so a lot of the stuff he spergs about, I can remember; either from direct experience, or because I've been laughing at weirdoes online long enough to have encountered it before.
Yes, the character Lou posted before is named Gadget Hackwrench. She's a motherly mouse from a 90s (?) cartoon called
Rescue Rangers. For some reason, furries in the 90s and 2000s started getting really, REALLY horny for her, to the point where there was even (allegedly) a Gadget Hackwrench cult started by Russian nerds. Some pics from their old website, dating back to at least 2008, if not earlier:



And here's a description on Wikifur which was written in 2011, full of TVTropes cross-pollution (WARNING: gross. Also, lol at this being so old that the coomer who wrote it was still using the terms "shemale" and "herm", instead of "futa" or "Totally Valid True and Honest Woman"):
I don't know how popular she is with furries who are under 30 (MLP porn long ago overtook the Gadget Hackwrench fandom, dooming her to a footnote in furry history), but Lou would have been exactly the right age and autism level to fall in love with Ms Mouse when her show was airing.
