Let’s get a little nerdy, but keep it chill. In the old church rules, “meat” meant the flesh of warm-blooded animals—think cows, pigs, chickens. Fish, being cold-blooded and slimy, got a pass. It was basically a loophole, like wearing sneakers with a tuxedo.
So, technically, you could eat beaver or muskrat on Fridays too, but nobody’s doing that. Thank goodness.
The idea was that by giving up the “fancy” stuff (land meat), you were making a small sacrifice. But fish was seen as humble, simple peasant food—never mind that we now pay $20 a pound for wild salmon.
Why do we eat fish on Good Friday? Surprising reason behind church law

There’s something deeply human about eating fish on Good Friday. It’s not just a religious rule; it’s a shared weirdness.
You know that moment when you’re at a work lunch, and everyone’s ordering the steak? You’re there with a sad-looking tilapia, and someone says, “Oh, you’re doing the fish thing?” You nod, and suddenly you’re in a secret club.
It’s like the opposite of a cool club—it’s a club held together by soggy batter and tartar sauce. But it’s ours.
