Sex slang: The latest juvenile gotcha

There’s a scene in “Wayne’s World” (1992) where the two protagonists trick a fuddy-duddy adult into answering to the name of a dirty body part.
“Ass sphincter says what?” Wayne Campbell (Mike Myers) asks.
“What?” a confused Noah Vanderhoff (Brian Doyle-Murray) replies.
“Exactly,” Wayne says.
Ha-ha. Gotcha.
Lately social media has been busting news anchors and other public figures for unknowingly saying sex slang. But at least one of the recent examples involves pretty obscure slang.
On Oct. 31, the Rev. Joel Osteen, best-selling author and pastor of megachurch Lakewood in Houston, made an embarrassing post on Twitter.
“A true friend walks in when everybody else walks out. A true friend doesn’t rub it in when you make a mistake. They rub it out,” he wrote.
That message sent social media atwitter and Osteen deleted the post. I guess I’m not up on my slang, because it turns out that “rub it out” is slang for masturbation.
Oh, gotcha.
And that expression has been used before. See the photo (and Internet meme) below of a sign outside Grace Baptist Church.
In another instance of accidental sex slang, a commentator on a Fox News broadcast said President Obama and his wife enjoy “fisting.” She meant to say “fist bumping.” Whoops. See the YouTube video here.
Or how about the news anchor in Canada who didn’t know the definition of “canoodle”? See that YouTube video here.
Frankly it’s getting pretty hard to keep up on all the slang. I’m always looking up unfamiliar slang words online, especially on Urban Dictionary. So have your giggles, people, and cut these folks some slack.
