Shmuckery
The art of being a shmuck (not to be confused with schmuck, whose meaning is completely different). In modern times, it is generally used as a negative connotation, but it can be used as a neutral connotation as well. Its meaning is generally ambiguous, and most people who use the word can draw their own conclusions to what its meaning is.
My friend Darwin is going out with his other friends tonight. I hope they're not up to any shmuckery.
