Has a reverse microwave been invented? Like something that cools stuff off fast, like a freezer, but faster. I thought of this when I wanted a soda while eating spicy Doritos and I wanted a drink but what I got wasn't cold.

liquid oxygen
There's the blast chiller, but it's quite slow.

stop drinking sugary jews, you cock sucker.

Such a thing would use more electricity than an A/C running for a whole hour
No, not efficiently yet

no, but you can use a peltier to cool small amounts of liquids quickly

or explode your can, because that shit drops the temperature to -(insert yor lucky number here) °C in a instant
>>54931127
just reverse the polarity of your microwave
Anti-Griddle. https://www.youtube.com/watch?v=xpdDzaNhX9M

already does it with aluminium automagically.
Try it OP.
You can achieve that by blasting whatever it is you want to cool with a fire extinguisher. It'll be rather expensive though.

it's called a refrigerator.
He closest there is to that are freezers so cold with black walls that absorb all incoming radiation operating at extremely low temperatures that absorb high amounts of heat from the object inserted in it
They cost a fuckton both to produce and to maintain operative

You mean like a blast chiller, flash freezing, or an anti-griddle?
the problem is that the rate you can extract heat from something is determined by the difference in temperature. Cooling a 50-degree can of soda to 40 degrees happens slowly with a 40-degree cooler because of the small temperature gradient. Attach it to a -100 cooler and you'll cool it down rapidly. You'll also freeze water out of the air and cement the can to the cooler, flash-freeze the soda thats touching the can wall while the center is still liquid, and other entertaining things.

Semi-serious answer:
Unfortunately, heating and cooling aren't perfect opposites of each other.
Due to the underlying physics, it is easier (meaning, more possible to achieve using more simple mechanisms) to heat something up than to cool something down.
For example, a refrigerator cools the inside but uses more energy to do so than the equivalent amount of heat-energy removed from the contents. You can kind of sense this by how hot the outside back panel of the unit gets - if you took that heat and put it back into the refrigerator, the contents would actually heat up more than the ambient temperature of the room.
To the point, a microwave directly heats something by dumping energy into it. To cool something down in the same direct fashion, you would need to somehow suck energy out of it.
I believe this is kind-of the principle used in laser cryogenics, but it only works on miniscule amounts of completely pure / single-element molecules, because the laser pulses have to hit the molecules at exactly the right frequency to dampen [reduce] their oscillation (and thus, their heat-energy). This is not doable for a big bunch of mixed up molecules like you would find in regular food or drink. Also, the principle of it costing more energy than is removed still holds - the laser itself gets hot :]

This is too cool.
