Mark of the Unclean 

A visible stamp on your hand the morning after a night out drinking.

Many bars that charge a cover will stamp people's hands before they go in so they know who has already paid. When the stamp a person received is still visible the day after, that indicates the person has not showered. Thus they bear the mark of the unclean.
Susie wanted to hook up with Tom in the morning, until she noticed he bore the mark of the unclean.

doctrine of unclean hands

Legal doctrine describing the absolute wrongness of setting your Starbucks down on the urinal while you drain the weasel. By your act, the coffee is forever unclean, and any attempt to rationalize it that it was just the bottom of the coffee cup that touched the urinal is futile. Osmosis by grossness occurs, and you are basically drinking other dudes' urine.
One of the essays on the bar exam last year involved the doctrine of unclean hands.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
