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.

An all-nighter is NOT simply staying up until the sun rises, then sleeping.
Jennifer felt like a zombie after having pulled two all nighters in a row during midterms week. "Really, it's not that bad after the 40th hour or so," she said, "...once you get past the hallucinations and the funny twitching thing your legs do."

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

The term is popular with college students who spend the night before an exam studying (or 'cramming'), trying to learn a lot of material in a short period of time. The term is frequently used in the phrase 'pull an all-nighter'.
1) We pulled an all-nighter to finish the report.

2) I pulled an all-nighter to study for my math exam.
