A term that can be used to describe a very toxic internet thread.

People associate popcorn with watching movies. Movies are known for being entertaining. A toxic internet thread is known for, again, being very toxic. So toxic, that reading it is like watching a movie, because both are entertaining. Just like what you do while watching a movie, you read a toxic thread, with popcorn. Popcorn comes from either a microwave, or a popcorn machine. Hence, the Popcorn Machine slang.

(Tip: Stay away from them.)
