Similar to binge-watching. A combination of "watch" and "marathon". A person is doing watchathon when they want to binge-watch anything. Movies, series, literally anything.
Person 1: Hey, wanna hangout later after classes?

Person 2: Nah, I've got plans. I'm gonna have a watchathon of the new season of Girl From Nowhere in Netflix.
