It’s one of the laws of the internet - if a lyric can possibly be interpreted as alluding to some kind of sex act, it will be. You just can’t stop people doing it. It’s like seeing faces in clouds.
All songs are about sex. Some are more explicit, like bird songs.
Your typical bird song translates as “Here I am, rock me like a hurricane”.
I see a new punchline in their future: “What if we add* more semen*?”
Is the term “bird song” something I’m supposed to know?
I think Oh Cum All Ye Faithful has Eileen beat hands down
Bird song. Song of bird. Vocalizations of the class Aves.
All of which perform one primary function, attracting mates while warning off rivals.
It’s fiction. Just like I could write a novel about the Civil War (or a rock song), somone could write about the Summer of 69 and not have experienced it personally.
A bad joke that I remember from that era:
Q: What’s the one thing that’s worse than grease on Olivia Newton-John?
A: Come on Eileen.
Next time you tell that joke, try it as “What’s worse than Olivia Newton-John in Grease?”
It makes more sense.
Also, Werewolves of London is about hairy vaginas,* Land Down Unde*r is about anal sex, and Peggy Sue is about an FtM transsexual whose prosthetic penis is made of whale bone.
I have the mind of a 15 year old! And I’m shocked, shocked I tell you to learn that rock n’ roll is about sex.
J. Starship, Miracles:
I got a taste of the real world,
when I went down on you girl.
What is unusual is when it is explicit and not a double entendre. Let’s face it, people are somewhat interested in sex.
At least there’s ZZ Top with the straightforward songs, “Pearl Necklace” and “Tube Snake Boogie”.
Q: What’s worse than sweat on Joan Jett?
A: Come on Eileen.
(That’s the version I remember from 8th grade.) 
Wait, didn’t five years or so ago Bryan Adams admit that not only was it *not *meant to mean the year 1969 but specifically the sexual position of 69-ing? I seem to recall a lot of his fans were rather disappointed to hear this.
As far as Come On Eileen, I was in my late teens in the 80s and when this song came out and yeah, the bad sexual pun occurred to us, but we never really thought or laughed about it that much. It’s kind of a Middle School-level joke. The thing about the song I always think about is how the beginning of it sounds like the theme to* Fraggle Rock*! (ignoring the short violin intro):
Or that the “Summer of 42” isn’t about dominos.
The Summer of the Answer to the Ultimate Question of Life, the Universe, and Everything
Someone on this board once argued that “Blood on the Coal” by The Folksmen was a reference to anal sex.
The answer changes every time he’s asked. But as I said, the song’s co-writer specifically said it’s not about sex and doesn’t thinks Adams even had that thought during the writing process.
Aye, this is totally true. Take any song and replace the word “love” with “drugs”, for instance.
Drugs Walk In
Why Cant This Be Drugs
I Can’t Stop Druggin You
Drugs In An Elevator
Also, I don’t think ‘The Hindenburg’ is going to catch on as a measurement unit for semen.
Didn’t the Beatles sing a song requesting multiple simultaneous money shots?
Come together
Right now
Over me
Drugging you is easy 'cause you’re beautiful.
Think about it, there must be a higher drug. Bring me a higher drug!
I drug you baby, and if it’s quite alright I need you baby to warm my lonely nights.
I’m hooked on a feeling, I’m high on believing, that I’m in drug with you.
Can you feel the drug tonight, the peace the evening brings?
Because I can’t stop drugging you. Oh no I won’t stop drugging you. Woah I can’t stop drugging you. How could I even try?
I drug you Lord, and I lift my voice, to worship you oh my soul rejoice.
And it might just save your life… that’s the power of drugs. Feel the power of druuuUUuugs.
Sometimes I am frightened but I’m ready to learn of the power of drugs.
I’ll be here all week folks!
