It’s digital nirvana: two highly searched proper nouns followed by a smutty entendre, a headline that both the red and the blue may be compelled to click, and the readers of the site can have a laugh while the headline delivers great visibility out on the Web.
"A smutty entendre"? I had never seen entendre used this way, as shorthand for double entendre, but if chauvinism can stand in for male chauvinism and graphic for pornographic, there's no reason entendre -- which English uses only in double entendre, a phrase with two senses, one usually risque -- couldn't take the same path.
But it hasn't gone more than one baby step along the route, a web search suggests. "An entendre" appears 15 times in Nexis newspapers, with citations back to 1988, if we throw out the uses (another 20 or so) that are explicit plays on double entendre -- "barman, give me an entendre and make it a double," and so forth.
Some of these entendres seem to be plain misuse: The idea that Chicago had 400 famous people "was an entendre, a joke, a tongue in cheek," said a founder of a social network there. A student music reviewer used the word to mean simply a non-dirty pun: "Musicaphile ...[is] etymologically sound ('sound' is an entendre though granted not a very funny one)."
But those who employ the naked entendre generally intend it as Carr did, as a short form of double entendre. From the US: "[Mae West] could deliver an entendre just perfectly." From Australia: Dame Edna "adroitly pivots on an entendre." And from England: "The 'Confessions' movies were 'Carry On' films minus an entendre."
Google News takes the solo entendre back to 1969 -- "[she] can put more into an entendre than an old vaudeville comic" -- but again, examples are sparse. Even Google-wide, there are only 360 uses (if the words double and triple are blocked). Still, most of those are recent and youthful, and if the usage does spread, that's where we'll see it first.
