Basically, the pressure will be the same in all parts of the bottle.
the pressure will be equal throughout the whole bottle
In that case, its pressure will increase. In the short term, its temperature will also increase, due to the energy required to squeeze it.
By reducing the volume of the bubble, you increase the pressure (P = M/V), and the pressure increases until the plastic material cannot hold it anymore, and it bulges outward, splits, and pops.
When you squeeze the cup against the window, you squeeze out the air from under it. Then the elastic plastic or rubber that the cup is made out of tries to return to its original shape. This causes an area of lower pressure under the cup, and the higher external atmospheric pressure pins it to the window.
Under the influence of external pressure the particles are forced together. Under the particles' own gravitational force the particles come together. Technically speaking there must be an external force to bring the particles of matter together. Another point to be noted is that when the particles moves so close to together that it crosses its critical mass a black hole is developed. But not always.

Classically ... squeeze it or heat it.

If you squeeze the bulb to expel most of the air, then release it with the tip under water, the pressure in the bulb drops and external air pressure on the surface of the liquid in its container forces the liquid into the dropper. When you squeeze the bulb again, you increase the pressure and force the liquid out.

We usually apply the term compression to the act of squeezing a fluid to force it into a smaller volume or increase its pressure. The term applies to gases as well as fluids.
pressure stress squeeze
A syringe.
polyethylene
We can't squeeze a sealed plastic syringe full f water because all the space in the syringe has already been occupied by water and as a result, there is no space left to squeeze. If we attempt to do so , then the syringe will burst or crack.
