I'm talking about gifs of a scene that don't show a complete motion, that are less than a second long. Like a swing moving forward, but it you see neither the start nor the end of the swinging motion before it starts over again.
Another one, similarly, is videos that end with a sound, like all the content on /r/perfectlycutscreams. It's not funny, it's not nice to look at or listen to, it's just retarded.
And like magic, OP went into a rage.
