In MMA?
Khabib smashing Conor for sure.
My all time favorite bully beat down was in middle school though. We had some kid that was already like 6' 3" 200lbs in 6th grade. He went on to play football at the University of Washington as a defensive tackle. Dude was just a fucking monster but a total softy and not a dick. Anyways, he was getting bullied by this kid at the bus stop all the time that was a few years older than we were. He was a freshman in HS I believe. He wasn't a big kid, but 3 years is a lot at that age. Anyways, one day this bully was making fun of the man child's generic pump sneakers. He had LA gear pumps instead of Rebock Pumps. This was just typical shit from this douche. At one point he asked the big kid if his mom was on welfare (she was), and the big kid finally snapped. He grabbed the bully who was facing away from him as he talked shit by his hoody and swung him around and off his feet and into the gully. The bully felt the power and you could tell by his face he knew this 6th grader who's balls had already dropped could handle him, so he continued with a psychological attack, as he was soaking wet in the gully. He claimed that he'd have the kid arrested and all this stupid shit that wasn't going to happen. The big kid jumped into the gully and literally dunked this fuckers head under the water. We were like oh shit, he's going to drown this fucker but were too scared to get involved with how big he was. He eventually let the kid up for air, and the fucker begged for his life. It was CRAZY but so satisfying because the dude had picked on me before too. Like most bullys, he learned his lesson and was super fake nice after having his ass handed to him.
