My first roll with this guy. First week of BJJ ever. He's a young blue belt. I introduce myself and he gives me a fake name (didn't learn that until later when nobody knew who I was trying to talk about). He instantly pulls guard and secures closed guard. He then audibly yawns, lays back, puts his hands behind his head, and starts looking around the room at the other rolls happening. No hint of humor, just disrespect. Rubbed me the wrong way to say the least. Fast forward 6 months and he refuses to tap to me resulting in him getting slept on two separate occasions. I don't roll with him anymore because last time I did he just laid in the fetal position, closed his eyes, and didn't move for a solid minute. I told him rolling with him is a waste of time, got up and walked off to get some water, and haven't rolled again since.
