A cinema and TV cliché that started in the 80's, lasted for about a decade and was used in several movies. A main character would dive over the floor pretty much impossibly, always shown in slow motion while shouting "Nooooooo!!" to prevent a catastrophe from occurring.
Even if there was a reason to perform a "No!" Dive, because something that bad was about to happen, it's impossible to do and also too cliché, it's not 1990 anymore.
