Definition: The word "zygotically" is a term that's often used to describe someone who doesn't put much effort into their work but gets away with it because of the nature of their position. Imagine being on a boat, and everyone else is at sea; you're still docked in port.
If someone is "zygotically good," they might be doing everything right except for getting caught up in the excitement of the moment (which is usually what happens). This person isn't taking any risks or putting effort into their work. They might not even care if their job gets them kicked out of their boat, as long as they get a promotion. For an example sentence, let's say you're working on a presentation at a conference. The other team members are all busy with different things (like having lunch together), while you're doing your thing in the back room. You might say, "I've been working hard for my entire career and I'm ready to put in the effort now!" This sounds like someone who's not putting much effort into their job. So if "zygotically good" means being a good employee who puts all of their energy and efforts into their work, then these words are actually kind of funny and unsettling.
