Word originating from a 17th century Dutch colony of what is now upstate New York. The town cobbler (who lived a quiet life) was observed one day at the local inn as he quaffed a pint of beer in less than a few seconds and, quietly placing the empty pint on the inn's counter, returned to work quietly in his shop. The cobbler's name was Matthias Von Klinker. Ever since, to Klinker a beer is to drink it very quickly without all the ridiculous glitz and show of a frat-boy beer-bonging.
I grabbed two beers - one for Mac, one for me. I looked down only to pop the top off of mine and when I looked up, Mac had Klinkered his and was ready for another.
