ULPT - request, how do I ruin canned larger?

So, there is a myth that when you're at the store buying beer you should buy warm beer if you're not going to immediately drink it because the product going from cold to warm to cold will make it go bad. This is largely false but that needs some explaining. Beer is on a race to oxidation after its been canned. Refrigeration greatly retards the effect oxidation has on the beer. So ironically, beer at the store that isnt in the fridge isnt being preserved as well before your purchase. Flavors from oxidation arent skunky or bad tasting in the traditional sense. Its like, wet cardboard or earthy paper. But enough to fuck with him I guess. People saying itll skunk it are ignorant at best. Beer can only be skunked by light interacting with certains acids within the hop. It quite literally makes the molecule that skunks produce, its kind of cool in a gross way but I digress. Skip the people talking about heat cycling it. They are wasting half your time. Put it outside in the sun until the day of, run down the oxidation clock and then rub your nutsack on the rims of them before the BBQ.
