Discuss this episode.

This week’s “Slang This!” contestant tries to guess the meaning of the terms beano (no, not the anti-gas treatment) and macing (no, not the stinging defensive spray).

In honor of the American Crossword Puzzle Tournament, Quiz Guy John Chaneski presents a puzzle about—what else?—crossed words. He has invited listeners to submit their own single crossers to quizguys@waywordradio.org. A single crosser is two related words that share only a single letter. The most elegant ones will be both long and from a fairly tight category.

A caller wants to know why those deep-fried balls of cornmeal and spices are called hush puppies.

An ESL teacher puzzles over how to explain to his students the proper pronunciation of the word “route.” He asks whether the pronunciation “root” has been “routed” by “rowt.”

A caller is curious about an expression her father liked to use off in the giggleweeds. What’s a giggleweed? And no, he didn’t mean marijuana.

More next week. Notice how we didn’t say, “Well, weed better be going”?
