Top Definition
a widespread custom at certain boarding schools in which sexually frustrated teenagers awaken at five AM, usually on Sundays (only hardcore kids have the stamina to practice this ritual on the weekdays and make it through classes), in order to hookup with another to evade the unjust coed rules and the prowling faculty. this habit is usually exercised by either the desperate or incredibly horny. (sixes, and six thirties have also become prevalent in these societies for the sleep deprived)
