(n.) Using the pharmaceutical drug, Adderall (or similar ADD treatment medication), in order to pull an all-nighter because you were too damn lazy to study beforehand. Nevertheless, this performance-enhancing drug is a fantastic study aid.

According to the Federal Drug Administration, "students with lower grade point averages of B’s or below use stimulants at a rate of 5.2%, compared to students earning B+ or above who use this medication at rates of only 3.3%."

Good job all you procrastinating, late-night crammers. And a special high-five to the Greek system, who uses these stimulants at a much higher rate of "8.6% compared to nonmembers who reported use at rates of only 3.3%."
