My brother and I are musicians and we shared a love of The Beatles growing up (I swear our mother was a Beatles groupie at some point, as all we ever heard growing up was how every single one of them were national heroes). So being the self-proclaimed wordsmiths we were/are, here are a few of the lyrics that we modifyed for our slang.
Walrus Gumble- Our sister is cooking tonight and it will not be pleasant.
Mean Mr. Mustard- Our uncle
Lucy in the Sky- Bullshit (example from grammar school: "I just got kissed by Mary-Anne!" "Lucy in the Sky you did!")
Hey Jude- my nickname for my brother
Penny Lane- we called shopping malls in America this when we moved there.
Ringo- mad, bonkers, insane, most oftenly used as "You've gone Ringo!"
Trying to make a dove-tail joint- trying to get laid tonight
Expert-textpert- this basically means don't be a tool or don't follow bullshit (ex: "Teacher says that conformity is great!" "Don't get all expert-textpert on me.")
Lennon- it's over your head; too smart for you to try to understand (example from our first year at an American High School: Our Dean: "Why do you insist on being difficult?" My brother: "Because you're expert-texpert with a twist of Lucy in the Sky." Dean: "What does that even mean?" Me: "Don't mind him, he's just being Lennon.").
Come on, keep your comrade warm- come on, let's hang out (usually said to a female, but was used as a "bros before ho's" type thing once or twice)
"Would like to go on a Magical Mystery Tour with Sgt. Pepper?"- would you like to get drunk tonight
Rubber soul- condom
Blackbird- my brothers' favourite song by them is "Blackbird," so he used this so describe things that were to his fancy (i.e. "She's a real Blackbird on the eyes.")
There are many more, and we still use most of them. This is what you get for growing up right by Liverpool with parents who saturated our minds with every album. Oh well, it makes for entertaining conversation.
