While the Stranglers meant something, well, very different. Though the song itself is very obvious and thus a good example for this thread:
…was a UK number one single boisterously praising Ecstasy; though as was presumably also the case with BBC bigwigs at the time, the drug references went over my fifteen-year-old head when it came out.
But don’t know much about agriculture.
Well, I don’t think they knew much about music, either.
My nomination is T-Bone by Neil Young. The only lyrics are:
Got mashed potatoes
Ain’t got no T-Bone
I’m going to go out on a limb and suggest that the lyrics mean he had mashed potatoes but no T-Bone*.
*[Which naturally was code for him having mescaline but no nitrous oxide]
Particularly when Chrissie Amphlett had a stage act to suit.
It’s easy. All the nouns are euphemisms for drugs and all the verbs are euphemisms for taking drugs.
Are you sure it’s not about fear of emasculation? 
Actually you could be right. Although according to my High School English teachers it is probably about alienation.
“Puff” was written as a poem in 1959 by Lenny Lipton, set to music by Peter Yarrow. Whether Peter, Paul or Mary were drug users I don’t know, but they had nothing to do with the words.
Lenny Lipton also wrote a book, Independent Film Making, that every film student in the 80s got to know.

How is that an anti-Vietnam war song?
You’re Breaking My Heart by Harry Nilsson
“I don’t need your war machines”, A clear reference to Vietnam
Speaking with Songfacts, Randy Bachman called “American Woman” an “antiwar protest song,” explaining that when they came up with it on stage, both the band and the audience had a problem with the Vietnam War. Said Bachman: “We had been touring the States. This was the late '60s, they tried to draft us, send us to Vietnam. We were back in Canada, playing in the safety of Canada where the dance is full of draft dodgers who’ve all left the States.”

The popular misconception was that it was a chauvinistic tune, which was anything but the case. The fact was, we came from a very strait-laced, conservative, laid-back country, and all of a sudden, there we were in Chicago, Detroit, New York – all these horrendously large places with their big city problems. After that one particularly grinding tour, it was just a real treat to go home and see the girls we had grown up with. Also, the war was going on, and that was terribly unpopular. We didn’t have a draft system in Canada, and we were grateful for that. A lot of people called it anti-American, but it wasn’t really. We weren’t anti-anything. John Lennon once said that the meanings of all songs come after they are recorded. Someone else has to interpret them.[1
The song’s lyrics have been the matter of debate, often interpreted as an attack on U.S. politics (especially the draft). Cummings, who composed the lyrics, said in 2013 that they had nothing to do with politics. “What was on my mind was that girls in the States seemed to get older quicker than our girls and that made them, well, dangerous. When I said ‘American woman, stay away from me,’ I really meant ‘Canadian woman, I prefer you.’ It was all a happy accident.”
Both from Wiki.
I read that quote at Songfacts. Doesn’t explain I don’t need your war machines,
I don’t need your ghetto scenes if it was just preference for Canadian women.
Surely the finest example of clear and concise messaging with no subtext. Ice T: Lets Get Butt Naked and F*ck (NSFW obviously)
Bachman was quoted saying that exact sentiment in, I believe, the 52 hour History of Rock and Roll radio special from the1970s. I didn’t believe him then, either.
If it’s an anti war song, it’s the weakest anti war song ever. Occam’s razor, a song that’s about big city American women being more worldly than a small town Canadian band was used to makes more sense. It’s not like anti war songs needed to be so subtle that you could only put two lines in a song. And why make an anti war song about women?
Since we now have 3 of the original band members saying it was about American women, I think I’ll take their word for it.
Women - Foreigner
And yet, Bachman explains it here: https://www.youtube.com/watch?v=4xtRR61tklU.
Lyrics are indeed open to interpretation, but the message is clear. Even at 10, in 1970, I heard the anger in the song and knew it was about Vietnam. Yes, even at 10, I questioned why we were fighting in a faraway place, against people that looked like me, and why men were dying on the TV news every night.
Edit: American Woman is the Statue of Liberty
Let me clarify my position:
I didn’t mean to argue it was an anti war song. My disbelief in Bachman’s explaination is that he said that it "isn’t anti-American women, instead it is pro-Canadian women ". I think he’s lying: I think it IS an anti-American song, but that he’s hiding it behind the skirts (as it were) of American women. “War machines and ghetto scenes” and colored lights that hypnotize have nothing at all to do with the undesirability of American women. I think it is an anti-American song, and, at the time, I could see his point.
