1386 Lip Hoisting

I heard a radio ad for the Chapstick Company recently and it got me wondering. They were talking about the cool stuff their product does for your lips. Then they said find them of Facebook. I think they definitely were trying to tie in the lip and the face thing. Then they said you should go on Facebook to “get even more lip service from Chapstick.”
I get it.
They’re giving you service tips for your lips, so they are calling it “lip service.” They seem to know full well that the phrase “lip service” is out there. And they seem to be playing on it. Unfortunately, they don’t seem to know what “lip service” means.
Lip service means, essentially, fibbing. Blowing smoke. Lying through your teeth. A person giving lip service is often doing so with a forked tongue. You’re recognizing an idea with words but not with your heart. “He paid lip service to the ideals of democracy,” means he spoke all the right words, but was still talking out of both sides of his mouth
Which, come to think of it, probably does cause chapped lips.
Another phrase I’ve heard has a similar confusing meaning. “Hoist on his own petard.” The dictionary says it means, “undone by one’s own cleverness.”
But not literally. “Hoist” means raised up, like a car on a hoist. “Petard” sounds like a flag. So you sort of get run up your own flagpole?
But no. A petard is a bomb. So it actually means, “blown up by your own bomb.” No word on whether 40 virgins await after being hoist on your own petard.
So if you don’t want to be undone by your own cleverness, watch out how you use lip service.
America, ya gotta love it.
