Word(s) that only ever appeared in one (hit) song, ever.

Haha, I’d never looked at the lyrics to “Mixed Emotions” before. That is an unexpected lyric. “To-ing” and “fro-ing” from the same song might qualify too.

There is a choral song that we performed in my high school choir that includes “toing” and “froing” but I cannot remember much beyond something like

“oh vidroshki’s herds you wander
through the matra hills and yonder
hunting toing and froing”

the bass melody still stuck in my head but no dice googling. not sure it counts anyway, since not a hit song— just made me think of it.

"To feel a pulsing from chanter to mountain"

Spandau Ballet - Musclebound

Queen's March Of The Black Queen: "Everything you do bears a will and a why and a wherefore"

Not sure it was a hit per se but Clifford T. Ward's 1973 single "Wherewithal" includes a couple of likely candidates: "wherewithal," "nonpareil"

I don't know where this thread stands on possibly invented words, but Rosie Vela's "Magic Smile" (top 30 hit on the UK and US AC charts) has "keenovay", which I think she said at the time was an Indigenous term for sexual congress.

Oh boy, do I have a thread for you:

Rusted Root Neologisms

ommaway

oombasayou

bubadasayoububadeeyon

Does "Dynasty" appear outside "Kiss"?

“TV Party” (EP version)

Was "TV Party" a hit song?

'Percentage' in "Hold Me" by Fleetwood Mac

%-age is in Traffic "Low Spark of High-Heeled Boys," well-known but not exactly a hit.

I wonder if any other hit songs contain the name 'Adolf', other than Games Without Frontiers.

The Hitler Rap (To Be or Not to Be)

Whereas Britt ...

Two contenders from Ray Stevens' Mr. Businessman (US #28): 'sinuses' and 'harlot'.

It also opens with 'itemise', but ofc that word was revived a generation hence by the Manics. A two hit word maybe?

"Bonaparte" in Gilbert's Nothing Rhymed?

Bonaparte also in the polish national anthem...

"Bonaparte's Retreat" was a #4 hit for Kay Starr, US Billboard 100, 1950. Later a minor hit for Glen Campbell.

I was recently doing an NYT crossword and got the clue "oil-based paste mentioned in 'Lucy in the Sky with Diamonds.'" Plasticene.

This led me on a slight detour through some Elvis Costello lyrics that include Bakelite and cellophane ("No Action" - not a hit - and "Watching the Detectives" - which reached #15).

"The Other End of the Telescope" barely charted but has a line about "a shellac of Chopin."

"Cellophane," beyond "Lucy" and "Watching the Detectives," also pops up in the opening line of SR-71's "Right Now" (#2 on the Billboard Modern Rock chart).

"hen fap"

Doctor C., upon reflection, "cellophane" is also in "Abacab."

In this regard it may be one of the more common uncommon words in hit songs.

To stick with the topic of industrially useful chemical compounds, "Tramp the Dirt Down" includes "tarmacadam," which may be its only appearance.

How do we feel about proper names? Sting has Krushchev and Pinochet; Costello has Chamberlain and Oswald.

Benny Hill's "Ernie (The Fastest Milkman in the West)" has 'clatter', 'milkcart', 'pasturized', 'macaroon', 'crumpets', 'goldtop'.

... no. 1 single in the UK btw.

In general proper names might be a little too 'easy,' but they can be still fun imho. "Khrushchev" is on both "Killer Queen" and "We Didn't Start the Fire," sadly.

Surely "pasteurized" shows up somewhere else --- isn't in some sneering 60s and/or new wave song about the minds of people with dumb mainstream ideas, etc.?

Bravo for finally unseating "macaroon" from "Sweet City Woman," which I put forth almost ten years back!

How about "anaesthetized" from "Radio Radio"?

Or, rather, "anaesthetize"?

tbh 70's UK novelty hits (like "Ernie") are a gold mine for this thread, just off the top of my head there's "Matchstalk Men and Matchstalk Cats and Dogs" by Brian and Michael - another no. 1, folks - yes, you read that right, matchstalk.

"Anaesthetize" has a couple of appearances upthread, I fear.

Two contenders from Ray Stevens' Mr. Businessman (US #28): 'sinuses' and 'harlot'.

The single didn't chart, but "harlot" appears in Dylan's "Jokerman", which received a lot of airplay and is probably his best-remembered song of the 80s.

If we're counting compound nouns, Nine Inch Nails' Wish is probably the only song that won a Grammy to include the word "fist fuck".

Electroencephalograph

"Makings," in Stevie Wonder's "Master Blaster (Jammin')." A much bigger hit than its present-day profile would suggest.

Nope, from Lou Christie's #1 hit "Lightning Strikes":

Listen to me, baby, you gotta understand
You're old enough to know the makings of a man

Damn!

Fish in a barrel here, but "hermeneutic" in Scritti Politti "Lover to Fall".

Hit single?

Fair point, though it seems like that ship has sailed several times upthread.

sideboard - Chas & Dave

I think Chas & Dave have quite a few of these.

“Sideboard” in “Come Together” also

But did that reach the dizzy heights of No. 55* in the charts like "The Sideboard Song" did?

(It only reached 55? What the hell?!?!)

Chas & Dave's "Snooker Loopy" (No. 6 in the charts) has:

snooker
baize
boggles
Taff
gaff
barnet
sod

The lyrics for Snooker Loopy are so precise and expressive. I love them.

'boggles' is in Starshaped by Blur (not a single, though)

"well-thumbed" in Bowie's "John I'm Only Dancing"?

Surely surely ba-burly this has already been mentioned, but in case not:

virtually every single word in "The Name Game" by Shirley Ellis (U.S #6)

'jugulate' in Lisztomania

also, 'Lisztomania'
