When an individual manages to be in bad condition to perform in an upcoming event the next day (e.g. a festival, party, exam, work) because of irresponsible behaviour (e.g. drinking too much) the previous day.
"Man, I failed my driving exam. I pulled a huge Seba'tje yesterday."
"I got fired today.. I came in work drunk.. I pulled a huge Seba'tje last night."
"I knew I should've saved my energy for the music festival today. But somehow I managed to pull a Seba'tje yesterday night, so now I feel like shit.
