Mark Sanford (R-SC) is a well-known "values" politician who managed to invent a whole new euphemism without even uttering it (see section below). First representing South Carolina in the United States House of Representatives from 1995 to 2001, he later served as governor from 2003 to 2011.
 That's not what they called it back in my day
After going missing for several days in 2009 (during which his staff tried their damnedest to pretend he wasn't), it turned out he was having an affair with a woman in Argentina. As the most publicized cover story his staff could come up with was "hiking the Appalachian trail," the phrase entered the political lexicon as a euphemism for a secret tryst (tryst itself meaning; "When people are sneaking to meet, notably as secret lovers"). The staff did not know that it was "Naked Hiking Day."
Most notable was his reaction to being caught. Instead of trotting out the children and wife, and begging forgiveness, he instead blubbered through how the woman he was having an affair with was his soul-mate, but also how much he regretted hurting his (rich) wife. In many ways, it sounded like a man who was truly wrestling with the fact that his heart and his religion didn't mesh. Not that it lasted long; he is back to being a "values" dick.
Speaking to the engagement level of his constituency and state representatives, he not only avoided impeachment for his lying and misuse of public funds, he was also elected back to the United States House of Representatives in 2012.
 Oh great
- Hiking the Appalachian Trail alone, is it safe enough? Substitute the euphemism in the "Other Answers" section for the lulz.
