Midwit cuckoo 

A midwit, or someone or middling intellect, who gets caught up in some form of mass hysteria. Strong supporters of a nanny state mentality to the point of insanity, and excellent examples of the Dunning Kruger effect in action. Named after the John Wyndham novel "the Midwich Cuckoos".

"Look at these midwit cuckoos, they want all dogs put down because some child got bitten by one recently."

"This guy says all humans must be exterminated to save the planet. What a midwit cuckoo."

Homer: Yeah, and if you get kicked out of that one you’re going straight in the army where you’ll be sent straight to America’s latest military quagmire. Where will it be? North Korea? Iran? Anything’s possible with Commander Cuckoo-Bananas in charge.

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."

cuckooing 

(verb) A crime where a drug dealer befriends a weak, old or otherwise vulnerable person, then takes over their home and uses it as a crack house.

"Cuckooing is a new type of crime which involves a drug dealer befriending a vulnerable individual who lives on their own.

Like a cuckoo, the dealer moves in, takes over the property, and turns it into a drugs' den."

(BBC Inside Out, March 23rd 2007)
