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.
12 step recovery jargon referring to someone new who talks about how great life is, now that they'resober. Usually meaning that the person is out of touch with reality.
The new guy seems pretty happy for a dude who has no job, no money and no family. He must be on a pink cloud.
