An idiom used to explain how a seemingly negligible or "weightless" variable can have a massive, tangible impact on an outcome.
It refers to the physics concept of radiation pressure. Because light carries momentum, the sunlight hitting a city like Chicago on a clear day actually pushes down on it, adding roughly 300 lbs of physical force to the city's total weight.
Example 1:
Person A: "I only changed a single line of code and the entire server crashed. I don't get it."
Person B: "Chicago weighs more on a sunny day!"

Example 2:
Person A: "I barely touched the gas pedal and we spun out!"
Person B: "Chicago weighs more on a sunny day, man."

Example 3:
Him: "She broke up with me just because I didn't hold the door open?"
Her: "Chicago weighs more on a sunny day."

Example 4:
"If I had found my keys ten seconds faster, I'd be here. Chicago weighs more on a sunny day."

doing everything EXCEPT what you are supposed to be doing
You and a friend get in your truck to go somewhere and you left your keys inside so you go back in to get them. Once inside you get sidetracked by finding something else you remembered you forgot and then something else and something else until you take so long that your friend gets concerned and comes looking for you, finding you with your hands full of stuff but no keys.
Friend: Are you coming? What is taking so long?
You: I been lookin for a worm weight. I know where one is but I thought I might find another one somewhere in here.
