And now, "jump the couch" has been named the Slang of the Year by the editors of the Historical Dictionary of American Slang.
The dictionary defines "jump the couch" as exhibiting "strange or frenetic behavior."
"Jump the couch" began popping up just a few weeks after Cruise excitedly professed his love for new flame Katie Holmes by leaping onto the guest couch during the May 23, 2005, Oprah Winfrey Show.
The phrase has since appeared in The New York Times, The Dallas Morning News, and innumerable blogs around the world.
Runners-up for Slang of the Year include Floodweiser, which is the canned water Anheuser-Busch donated to hurricane victims, and Spokesweasel, which is a public relations representative.
