According to The Onion, a group of co-workers met up for drinks in Brookline, feeling "professionally obligated," which became increasingly unpleasant over the course of three minutes.
For those unfamiliar with The Onion, it is a satirical news source covering topics from politics to sports to science. The "News in Brief" section of the website is dedicated to short paragraph gags with made-up quotes and situations.

For Brookline residents and folks familiar with the town, there are a couple of bits of (probably) unintentional humor: ProVantage Solutions, where the excruciating after-work drinkers work is a real company, but the headquarters are in Raleigh, North Carolina--none of their offices seem to be in Massachusetts. The bar in which the co-workers meet up is Freddy's Bar and Backroom-which isn't actually in Brookline, but in Brooklyn.
When it comes to a joke, artistic license is allowed.
