Spin-off from "mug shot", a chug shot is a picture of someone "chugging" a beverage (often alcoholic in nature). These images are mostly seen uploaded to social networking web sites for people to make themselves look cool. Unfortunately, these snapshots of a great time could hinder the person's credibility if viewed by prospective employers.
1. Bob was about to land a great job with Boeing, right out of college, until the HR department searched his name and saw his chug shot from last weekend. They hired Steve instead. Bob is now forced to live with his parents and work for Home Depot.
