Carlos, the Spanish and Portuguese form of Charles, is derived from the Germanic name Karl, meaning "man" or "free man." It has been a top-360 baby boy's name in the U.S. every year since 1900 and was even listed in the top-10 every year between 1970 and 2012, per the Social Security Administration. It's the name Zach Galifianakis's character in "The Hangover" gives to the baby he and his friends find in their hotel room. It can also be a nod to musician Carlos Santana or Big Time Rush singer Carlos PenaVega.
