Some have got it right here in that it stands for pounds per square inch. The context they are using it is wrong though. We don't think of using the term as an indicator of depth at all and we don't need to worry about it "crushing us like an egg" as the human body is mostly water and doesn't compress, just the air spaces (our airways and sinus cavities) and this issue is dealt with by inhaling breathing gas that itself is under pressure in the tank, which brings us to where we DO use the term PSI.
We use it as a measurement of our gas supply in the tank. An aluminum 80 cubic foot tank, for example, when filled, typically has 3000 PSI of breathing gas in it. As we use that up on a dive, that number goes down and is shown to us on a pressure gauge that's marked off in PSI that's connected to the tank valve.

Pounds per square inch. The weight of water pressing on you.

pounds per square inch.
the further down you go, the more pressure you have...so if there is a PSI of 5000, that means there is 5000 pounds pushing against every inch of your body.
basically that would crush you like an egg.

Pounds per square inch..as in pressure.

Pound Per Square Inch. It has to do with you depth.
