noun
*| \ ˈsta-ndərd ˈsi-stər-in-ˌlȯ yü-nət *
Abbreviation: SSILU
Symbol: 𝓢 or SIL
Definition:
An unofficial unit of mass equal to 300 pounds (136.08 kilograms), used to simulate high-risk, real-world human load scenarios in mechanical, structural, and transportation systems. The SSILU is commonly applied to test the failure thresholds of furniture, vehicle seats, elevators, bicycles, airline cabins, and public patience.
Etymology:
Originated in post-war American slang, the term is derived from the stereotype of a loud, heavyset female relative—often portrayed as emotionally volatile and structurally compromising—whose presence tests both family dynamics and infrastructure load-bearing capacity. While non-literal, the “sister-in-law” archetype evokes maximum physical and psychological mass concentration in civilian environments.
Technical Classification:
Measurement Type: Anthropomorphic Load Unit
Mass: 300 lbs (≈ 136.08 kg)
Field Use: Structural stress testing, emergency engineering simulation
Design Benchmark: Most consumer goods are not rated past 0.8 SSILU

Get the ice's first law of maps mug.Car-ogance law states that whenever cyclists raise valid questions about their safety or discomforts that within three responses car owners will try to bend the topic/discussion about the own responsibility and unsafe behavior of that cyclist.
Example 1:
"Yesterday I got hospitalized because I got doored by a car-owner that opened his door"
"Those damn cyclists should wear a helmet. It is your own fault!"
"You're showing car-ogance and should keep your attention on the traffic instead of opening the car door without looking"
Example 2:
"I don't feel safe on the roads of Amsterdam sharing the road with SUV's."

"You are showing car-ogance and should be aware that other people are also in traffic without a car."
