A euphemism for a man's penis (man) and his testicles (the boys). It is advisable to use this euphemism when referring to an erect penis and shriveled set of scrota. In a reversal of this condition (with a flaccid penis and an engorged set of scrota), the "man" looks more like an "old man."
Got into a bar fight last night. That Asian kid went all kung fu on me, until I kicked him in his man and the boys!
Those pants are way too tight. Definitely queer. Why, I can see the outline of your man and the boys!
