I would've worded it as "petulantly delaying sleep". One is being immature and frustrated at the lack of planning and control in one's life, so one retaliatorally "plays" when one actually has the power to decide. There was an article not too long ago about overly-controlled/time-regimented children doing this same thing. When they have no power over how to spend their day, they decide to control their night, to their own detriment, health-wise.
