A term used to describe the act of staying awake throughout the night (sometimes more than 24 hours at a time). Usually, one pulls an all nighter so that they can get a project or report done, or simply because they're having sex. There is no valid reason to pull an all nighter other than these provided. The exception is when you're drunk, because no one knows why they do anything when they're drunk.
