Ah yes I still remember that day.
Early in my whitest of white belt days, I've experienced kob's from other white belts and it wasn't THAT bad, it was tolerable and I could escape easily. That changed when I rolled with one of the BBs. Middle aged Japanese guy.
We slap hands, I fight for lapel grips and I get them, and I was thinking this wasn't ba....next thing I knew I'd been taken down, and the KOB from hell was coming. And it was bad. Really bad. Dude smiled at me from top and told me to escape, I couldn't even explain that there was no way I could escape. So I tap. And the exact same thing happens 4 more times.
