(CNN) - Is Obama ditching his signature fist bump?
According to Tuesday's press pool report, the Illinois senator refused to bump fists with a boy as he was touring the Eastside Community Ministry in Zanesville, Ohio.
As the boy outstretched his first, Obama said no and added, "If I start that ..."
His voice then trailed off.
The presumptive Democratic presidential candidate popularized the move last month when he and his wife Michelle bumped fists on the night he formally captured the party's presidential nomination.
Watch: The famous fist bump
Video of the duo fist bumping became widely popular on the internet, leading the Washington Post to declare it “the first bump heard ‘round the world.'”
