A "Burnsie" (pronounced burnsy) is where you throw back some hard liquor during normal business hours, enough in fact that it's all over your breath and you slur your words when you get back to the office. Those that have the cajones to pull a Burnsie are generally high up enough in the company that nothing will ever come of it. The underlings however are fully aware that a Burnsie has taken place.

Usually a Burnsie happens over a lunch with sales people.

The "Half Burnsie" which is the same lunch, less liquor and you don't slur words.
