A euphemism for masturbating in public, first coined by New York Jets tight end Kellen Winslow II, who was found by police masturbating in his car. When asked for an explanation, Winslow claimed to be looking for Boston Market, but was lost.
Police officer: "Sir, are you masturbating in your car?"
Guilty culprit: "No officer, I was looking for Boston Market"
