Boise, Idaho ? Among the most famous excuses ever given for questionable behavior, “I have a wide stance” must fall somewhere between the schoolchild’s favorite “the dog ate my homework” and President Clinton’s “I didn’t inhale.”

But Sen. Larry Craig’s contention – made just after his arrest in a restroom sex sting – has permeated the public consciousness, showing up as more than just the punch line to late-night talk show jokes.

The online Urban Dictionary defines “wide stance” as a euphemism for a closeted homosexual. David Kurtz of the blog “Talking Points Memo” called Craig’s wide stance claim “The Best Legal Defense of 2007.”

Craig uttered the now-famous phrase after an undercover police officer at the Minneapolis airport arrested him on June 11, according to police reports.

During questioning, the senator said he simply has a wide stance when using the restroom and was not using a code to solicit gay sex.

Will “wide stance” last as long in popular usage?

“You search the blogosphere or even newspapers and you’ll find a lot of references to it,” said Grant Barrett, co-host of the nationwide public radio show “A Way With Words” and author of several slang dictionaries. “People are toying with the words, seeing how it feels on the keyboard.”

So what makes a new phrase last? It has to be useful, Barrett said, and it has to be able to stand alone, without a reference to its origin.

“There’s a lot of political slang that hasn’t lasted,” he said. “The test will be when the story’s old hat and then we’ll know for sure.”
