Some schools have a time policy for professors which allows students to leave if the instructor does not arrive after a given amount of time. Clock Blocking is when a professor arrives just before this time expires.
It was 11:14 and we were so close to having class cancelled when Dr. Jones walked in and totaly clock blocked us.

When you're looking forward to leaving work early or on time, but are kept late either by a new assignment from your boss or a chatty coworker.
I was all set to rush out of work at 5:00, but then I got totally clockblocked by my boss and wound up staying till almost 7.

When you're having a sexual dream and it's interrupted by your alarm clock.
I was about to screw this chick in my sleep at 7:59 and at 8, I got a clockbock. The alarm fuckin clockblocked me. Dirty bastard.

When your alarm clock goes off at the wrong time, preventing you from sleeping in.
Jane: "I forgot to reset my clock last night for daylight saving's time, and my alarm went off an hour early. There goes my beauty sleep."

John: "You, my friend, have been clock-blocked."

When you are having a dream involving intense sexual content, when all of the sudden your alarm clock goes off and you wake up in the middle of it.
I was banging Meagan Fox in my dream last night, but i was totally clock blocked when my alarm clock went off as I was about to get a blow job.

Effectively a cockblock, only by someone who simply spends all their time doing something else.
