The act of preemptively cheating on your significant other *just in case* they cheat/are cheating on you. That way if they ever cheat, you have an ace in the hole.

Very similar to the well documented Prisoner's Dilemma.
Guy 1: You hooked up with Emily? Thought you had a girlfriend
Guy 2: It was just insurance, nothing serious
Guy 1: You don't trust your girl?
Guy 2: She went on Spring Break with a bunch of dudes, WTF am I supposed to think?
Guy 1: Yeah I feel you

Insurance is a big international industry employing thousands of people. It has a turnover of billions of dollars.
The Insurance Industry started at Edward Lloyd's coffee house in London in the late 1680s. Edward Lloyd's was a popular meeting spot for master mariners, merchants and ship owners. All the news about the departures of ships, their estimated time of arrival at the port to which they were sailing ,and the cargoes being carried was discussed over coffee and something to eat. Lloyds rapidly became the place where ships and their cargoes were insured against loss at sea. Today Lloyds of London is still the leading marine and specialist insurance market in the world.
