There are sayings that you learn when you are growing up that you just learn to say phonetically and after a few years of just saying a phrase, you stop and think about the phrase and question what the fuck does that mean?
My mom says shit like that all the time and i've figured out when to use the phrase, but i'm left clueless as to what it actually means.
"I didn't want to upset your apple cart"
My mom says this when she sarcastically implies that she cares about my complaining.
Kill: Mom, why are we inviting those nazis to dinner?
Mom: Oh, i'm so sorry i did that, i forgot how important every dinner is for you, "I didn't want to upset your apple cart."
Now, my mom could be saying something totally different and my fucked up four year old mind translated it this way and has stuck that way ever since. Or it could be that everyone can plainly see the apple cart is a symbol of my subconscious desires and ego and all that psycho babble and is metaphorically represented through simple things that common folk can understand: apple carts.
Here is a reference to the saying...i think
My dad also does something similar, but i am positive it's not part of common culture
When my mom says something nagging to my father he'll mock her by squawking like a parrot, whistling like a parrot and repeating the same thing.
Mom: "Jesse, it's been months since you've cleaned the garage."
Dad: " Jesss, it's been months since you've cleaned the garage, RRRARRRR, TWEET TWEET,"
He'll also flap his arms like wings to make his point.
What does this really mean? I get that it's mocking in nature, but essentially he is calling my mom a parrot? Are parrots nagging creatures? Not really. It might be that my dad feels like a "pet" that has to perform tricks for my mom. That makes a little sense. Hmmm, maybe i just figured this one out.
There are a ton other phrases that i can't think of, but i'm sure there are some you can think of
