look up any word, like dirty sanchez:
 
1.
A condition where a person falls prey to hypothermia by not wearing appropriate clothing in an urban environment.

This condition generally affects people who are trying to show off their rad tan, biceps or new tatto sleeve in cold weather.
"Dude, Jayden is in hospital.
What happened?
We met up for a macchiato and he was only wearing a singlet so he could show off his sweet new sleeve. One minute we were sipping micro-foam and the next he was out... The doc said it sounded like a classic case of urban hypothermia."
