A verb my frineds and I made up to describe when somebody gets massive amounts of damage inflicted to them. This could involve kicking, punching or any other form of impact-type violence. My friends and I came up with this word while playing an old fighting video game. There was this one move where the guy would do a huge heel kick, and usually kill the other guy in one hit with it.
*guy gets his face smashed in with a baseball bat*
"Dude, that guy just clop-dropped Jimmy!"
*guy gets kicked in the head and knocked unconsious*
"Nice job clop-dropping that asshole, Luke"
