Malarkey. This refers to words that are insincere and talk that is particularly foolish. The first known use of malarkey was in 1923 Exaggerated or foolish talk, usually intended to deceive. “This is a bunch of malarky!”
Interestingly enough, I actually thought the word malarky meant to lollygag, drone, dawdle, dillydally, twiddle one’s thumbs, muck about, shenanigan, piddle and putter, malinger about, or skylark.
My malarkish behavior is never to deceive. I am always leaning towards foolish behavior!!
“You will do foolish things, but do them with enthusiasm.”

Since Biden used it in his debates, it was one of the most searched words to know its meaning. For these sites (Chile) it is not known that’s why with your description, I add it to my knowledge. Regards.
