Ass o'Clock

A stretch of time in the early morning, generally around 4 A.M. to 6 A.M., which is either unreasonably late or unreasonably early depending on the context. Used to emphasize how late one has stayed awake, or how early one must wake up.

"We were all up 'til ass o'clock in a call, I didn't get any sleep last night."

"Mark has to get up at ass o'clock to go to work."

An unreasonably early hour.

I gotta get up at ass o'clock every day for the next month. I hate my job.

A time very late at night or very early in the morning when most people are or ought to be asleep.

My sleep schedule is ruined because my favorite YouTuber uploads at ass o'clock
