hospital surf 

Typically in an area with several hospitals in it, a person with no cigarettes or money, walks from hospital to hospital, scoping out the outside ashtrays fer smokable cigarette butts...After the last hospital is hit, you go back to the first...By this time, hopefully, there will be a whole new generation of fresh butts to smoke.

After Gennie locked me out, I was stuck fer a place to go, so to kill time, I hospital surfed, smokin' like a chimney the whole time.
