Meat Switch

At a Brazilian Steakhouse, they give you a small object to place in front of you. If the green side is up, they'll keep offering you more meat. If it's red, they'll pass by you. This "Meat Switch" controls how much meat you ultimately get.

Bob, you still eating?
No, I'm stuffed.
Flip your Meat Switch to red then, so they stop bothering you.
Gotcha

Meat Switch

A device that requires someone to flip a switch or depress a button. Normally placed into an serial task. To move forward an individual is required to flip or depress a button. Once done the next steps in the task can be started.

It is commonally used as a software version of a Molly Guard, a barrier to protect something from unwanted contact, especially a shield to prevent accidental deployment of software into production from automated Continuious Intergration and Developlment (CI/CD) setups. It could be inserted into any step in a CI/CD to require a human to consciously move forward.

You will need to click the meat switch before deploying the service to Production.
