Top definition
The urban practice wherein a man strolls the streets, fully clothed and in a belted trench coat, and slowly but covertly, though a side pocket, masturbates himself in the presence of fellow pedestrians and pasers-by. The benefit of the act is sometimes claimed to be expediency, but more likely is the ability to "get away with it," especially when ejacualation is achieved but not revealed.

"Why do you say Geoff's a wanker?" -- "I mean, literally, man. I ran into him on Halsted and he had just done a complete London Flog."

"How could you tell?" -- "Well, partly by the refreshed happy-ending look on his face, but mostly by the stain he had made on his trench coat below the buckle."

"Ewww . . . well, at least he kept it in his pants."
