cuckoo clock

When a man is having sex with a trach hole in a person's neck, deep enough to reappear through the mouth or other facial orifice, ejaculating at the top of the hour.

Cupertino cuckoo-clock 

When the iPhone of everyone within earshot goes off with an alert or meeting invitation at the same time.

Cuckoo clocking

The action of announcing the time and number of hours left in a work day at annoyingly short intervals.

"Seven thirty, eight and half more hours until quitting time."
"Stop Cuckoo clocking! Nobody cares how much longer we have to work today."
