Staying awake, usually with the aid of caffeine and cold showers, for over 24 hours. Usually a feat performed by overworked students, but also by physicians and programmers, and other individuals who refuse to sleep until having solved some mystery.

A study or work session that goes through the night; studying without sleep (usually a last-minute course of action).
