Way back in 2011, I wrote about the expression “full stop” (BrE for AmE “period”), specifically to emphasize what the speaker has just said.
According to a Christian Science Monitor blog post, the trend has continued and, seemingly, intensified:
Before announcing his presidential bid, former Maryland Gov. Martin O’Malley made clear in December his disdain for the CIA’s highly controversial interrogation tactics. “I don’t believe the United States should torture,” he said. “Period. Full stop.’’
More recently, George Washington University political scientist John Sides was asked
in May if early polls were relevant to who would take office: “They are not. Full stop.” A month later, Republican Rick Santorum, queried on Bruce Jenner’s decision
to become Caitlyn Jenner, responded: “My job as a human being is to treat everybody with dignity or respect – period, stop, full stop, no qualification to that.” That same month, Iowa pollster J. Ann Selzer discussed Hillary Clinton’s supposed political invincibility
in the Hawkeye State: “The reality is, this is a field where nobody has effectively stepped up to challenge Hillary Clinton, full stop.”
Just four days ago, in a speech in Kenya, Barack Obama said: “If somebody is a law-abiding citizen who is going about their business and working in a job and obeying the traffic signs and doing all the other things that all citizens are supposed to do, and not harming anybody, the idea that they are gonna be treated differently or abused because of who they love is wrong, full stop.”
