Napping far longer than originally intended. Due to faulty alarm clocks, massive sleep deprivation, or intense drinking the night before.
I was going to do my homework, but my alarm clock didn't go off and I overnapped.
The hell?? My test started a half hour ago, I overnapped again!
Jesse was late to class again; he's a pretty consistent overnapper.
