I don’t drink Mexican beer.

It's safer than drinking the water!

Having grown up in South Texas, the story was that Mexicans reused bottle caps, and bottles. Being Mexicans, they did not wash the bottles well. Thus, we gringo's used a bit of lime to clean the neck, and thought WTH, just dump the lime in the beer. It was interesting and we were lazy. So, we started a trend. Now thousands of metrosexuals use lime in beer and have no clue as to why.
