A
German term that originated in the northern regions of Hamburg that refers to erratic and often "trainwreck" style behavior from a middle aged man. A Jan can take on many forms, but often appears in the form of coffee addiction, intern harassment, STD
spread, an inflated sense of convenience, and
child like aversion to common things such as balloons, rubber bands, cilantro, and condoms.
How was your
weekend man? It was pretty
wild I pulled a Jan, might have gotten
fired, definitely didn't sleep, and now my intern won't return my texts.
