Being full of food .
The origin of filled to the gills comes from goldfish. They will eat and eat until they are stuffed to the gills and make themselves sick. They do not know when to stop eating. So stuffed to the gills is used as an expression for when one has eaten too much.
If you go fishing or even just go to the fish market, look down into a fish's mouth. You will see the gills on both sides and just after the gills in the oral cavity you will see the opening of the gullet. If you have a particularly well-fed fish, the gullet may show unswallowed food because the stomach is too full to hold more so, it is waiting to be swallowed. Humans don't have gills but the analogy can be appropriate when you feel you have swallowed more than your stomach can hold.

There is no literal idiom -- an idiom is a phrase that seems to mean one thing but actually means something else. The word "literal" means to take the words exactly as they seem to be.An idiom is a phrase particular to a language that is accepted for its figurative meaning, as in "That amazing shot blew me away." Everyone understands that this person means he was amazed. A literal idiom would be the usually humorous thing that happens when you take the idiom for its word for word, not accepted, meaning. That would mean that somehow the amazing shot actually created the air mass necessary to blow this guy away.

Oh, dude, so like, the phrase "stuffed to the gills" actually comes from the literal meaning of being so full that you're packed up to your throat, like a Thanksgiving turkey stuffed with way too much stuffing. It's like saying you've eaten so much that you couldn't possibly fit another bite in your mouth without exploding like a human piñata. So yeah, it's basically a fun way of saying you've overindulged to the max.
