quo vadis haircut
n.— «And for all of his 16 years giving Mr. Obama his “quo vadis” haircut—black parlance from the 1960s for close-cut locks—Zariff said he is not about to start ribbing Mr. Obama. “We do not tease about the gray at all,” he said.» —“For Young President, Flecks of Gray” by Helene Cooper New York Times Mar. 5, 2009.
