Yes, I've already found an explanation. That's not humour, just an idiom.
In English we usually mention glue (factory) in place of a soap in such a context, although there's no direct counterpart for this particular expression.
Also, it wasn't limited to horses and races, from what I've learned - any livestock deemed unfit for some reason (including misbehavior) was sent to slaughterhouse to derive the last ounce of worth, in the form of the glue/soap.

agogin, Now that I remember that Ricky is a chosen one, his admin status actually makes some sense.
Also, I've seen a clueless admin several times - he clearly had no idea what he'd been doing at the time but the tech obeyed him nonetheless, while flipping off everyone else in the room.

And now I'm flooded with guesses about that someone's identity.
If I'm right and that was an artificial idiot posing as Jerry, then this might be Jerry himself.
Otherwise - oh, where to start... Pinkie, Neo, that Byzantium purple guy with glasses, the Janitor...

So, Ricky is confirmed to be an admin?

#1430080, Looks like a deliberate mix and match. After all, the author is trying to convey their own story, rather than to brag about authenthicity of their fanfic, which it is not anyway.
Actually, it's funnier this way, leaves more to interpretation. For instance, I explain this with Jerry being a cleptomaniac moron on par with Wheatley.

That awkward moment when you're trying to make sense of a random Russian idiom and in the process of googling learn more than during the whole previous year...

IMO, he's trying to stroke his own ego in several different ways, but he didn't think it through and didn't realize they contradict each other and this can make him look like a moron again and again. Which is typical for him, from what I managed to read already.

#1428518, In the "Legacy" the developer guy starts frequently visiting the virtual world after the first film. He gained admin sysop status there and started doing some experiments. But he also had a life and so made part of his mind into a separate AI, who was looking like him and worked as his stand-in and second in command when he wasn't around. Then some stuff happened, the AI usurped him and the dev guy went into hiding for years. Then dev's son comes looking for his dad to have a talk about abandonment, gets sucked into the virtual world (I think the AI sent him the clue, but cannot remember) and thinks the AI is his father, because it looks exactly like the dev guy when he created the AI and uses this to pretend being him. AI also suckers him unto this racing tournament, but at some point drops the ruse and just goes full-on dictator like it was before son dropped in.

I was talking about Legacy, and I was wrong about details, apparently.

Also, since I remembered the plot of this movie a bit, I think this Jerry is an artificial idiot impostor/decoy, with the real thing actually wearing his hat and hiding elsewhere. The catch will be that they are both jerks and morons in equal measure, and the only difference would be the hat.

#1428114, Jerry, making himself a virtual God, can screw all his rules as he makes them, while never giving (willingly) such an ability to Ricky and the rest.

If I remember the movie correctly, the bikes cannot stop. You could dismiss the bike, but that would also dispel the wall (and I think you would be shot for spoiling the game).

"Racing" is a cooler sounding name for a gladiatorial game.
