Before you start feeling Victor Fries, well, it might as well be that your drink is already at (or even below) freezing temperature, but specific conditions hinder the crystallization of the drink. If the liquid is static, homogeneous, at rest, clean, etc. water molecules might not migrate in order to make a crystalline structure (This is, to make an ice crystal, molecules must arrange themselves in certain patterns) Many things affect the way water molecules crystallize. Dr. Masaru Emoto demostrated that certain sounds affect the way water freezes, Their experiments are very impressive.
Now, if you touch a bottle , you are indroducing a disturbance (maybe a small temperature gradient) which might be enough to unchain a cascade of events for the water molecules to aquire the kinetic energy to arrange into crystals,or if you touch the liquid itself with your lips, maybe you are introducing crystallization nuclei in the form of tiny particles of skin flakes, enough to start the freezing, which then continues rapidily.

This is called a metastable equilibrium. The Greek “meta” means something to be in the midst of something else. Therefore, metastable equilibrium is something philosophical, such as someone in a party, late at night, deciding if he(she) will go right away home, or if he(she) will stay a little longer for another cup of coffee (He, he..). In other words, a cold solution may be in doubt if it freezes or not.
Thing is, if you cool a solution of whatever very slowly, you will reach the temperature when that solution of something should begin to freeze, but the solution does not do that. The combined mixture of solute and solvent keeps freezing down, without actually icing. No solids are formed, until… Tchan, tchan, tchan… you put your warm fingers on it. The temperature you deliver to the contents of your drink is enough to break that metastable situation, and the thing, which is below the normal freezing point, feel the right to freeze, as it should have done, in principle. And, just for the sake of Nature, it begins to annoy you. It is nasty when it happens, isn’t it?
There is a nice trick, though. If you think your bottle of beer will bother you with that thing of freezing out and allowing the CO2 to spur the liquids and smear things off the bottle, you can do the following: secure the unopened bottle by the very neck, where there are no liquids to transfer heat to. With the fingers of your other hand, rub gently the bottom of the bottle, so that heat will flow from your fingers to the denser part of the metastable solution (gravity sinks the denser things, remember?). This heat transfer, if well done, will allow the heat to break the metastable conditions from the coldest parts of the solution, all the way up to the coolest part of it, rendering your future drink absolutely cold, as it should be, but not solid, as it should not be. The trick allows you to open up bottles of beer, to the amazement of all your friends. Don’t tell them the trick, jus do it!

I don't know but it is absolutely amazing when this happens. i had a bottle of water in my car last Winter, when I touched there was the same freezing effect.

When you touch the bottle, nucleation points are created.
Without nucleation points, a liquid can be supercooled without it solidifying. The same thing happens with vapor turning into a liquid. That's why they can "seed" clouds to create rain. They create nucleation points for the water to coalesce around.
Nucleation points are also created with you drop Mentos into diet coke.

the temperature of the bottle is the same or even more as the freezing point of the beer
so beer freezes wen it is subjected to its freezing point....... tht comes from the bottle

Maybe because you keep them in the freezer
