This is a list of names in which the categories include modern slang.
BugsymEnglish From a nickname derived from the slang term bugsy meaning "crazy, unstable". It was notably borne by the American gangster Benjamin "Bugsy" Siegel (1906-1947).
DarrenmEnglish The meaning of this name is not known for certain. In the spelling Daren, it was used by the novelist Zane Grey for the central character in his novel The Day of the Beast (1922). Grey may have based it on a rare Irish surname, or perhaps created it as a variant of Darrell. It was brought to public attention in the late 1950s by the American actor Darren McGavin (1922-2006; born as William Lyle Richardson). It was further popularized in the 1960s by the character Darrin Stephens from the television show Bewitched.
