*headline in The New York Times of 2.12.12.
From Online Etymology Dictionary:
early 14c., “quality of being humble,” from Old French umelite “humility, modesty, sweetness” (Modern French humilité), from Latin humilitatem (nominative humilitas) “lowness, small stature; insignificance; baseness, littleness of mind,” in Church Latin “meekness,” from humilis “lowly, humble,” literally “on the ground,” from humus “earth,” from PIE root *dhghem-“earth.” In the Mercian hymns, Latin humilitatem is glossed by Old English eaðmodnisse.”
“Humblebrag means a statement which at first seems self-effacing, but in actual fact calls attention to something of which one is proud. Humblebrag may be used as a noun or an intransitive verb, which takes no object. Related words are humblebrags, humblebragged, humblebragging and humblebragger. Though humblebrag appeared for the first time in 2010, it is already in the Oxford dictionary. Humblebrag was coined by the writer and comedian Harris Wittels, who also produced and appeared on the American television show Parks and Rec. Wittels first used the term humblebrag on his Twitter account to point out statements that qualified for the term. In 2012 Wittels published the book Humblebrag: The Art of False Modesty. Wittels died in 2015 at the age of 30.”
