Title says it all, my one always sticks out in my mind. I was rolling with a fellow white belt and he was getting the better of me, I remember I pulled guard as I was really out of breath and threw my legs up to try and secure an armbar from the bottom, I soon realised that I wasn't using my hips enough, what I noticed more was that he didn't try defending the armbar at all when I attempted it. I got in position again, threw my hips up and got the leg over, soon I was on my front with his arm between my legs, I straightened up and secured that armbar like there was no tomorrow. Literally from having no BJJ experience to securing this, I felt like I'd just pulled this off as if I was in the main event of metamoris lol. It's always stuck with me as one of my favourite submissions I've pulled off just because it was the first I'd successfully done. Just wondering what everyone elses was and if they remember it?
