Standard Sister-in-Law Unit
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

Obama State of Union Address mentioned Citizens United with an "in your face" to the Supreme Court. Justice Alito visibly disagreed.

Citizens United is for good for citizens the same way rat poison is good for rats.
Citizens United sucks. I wanted Joe Shmoe, who seems kind of honest, to win the Senate seat and go to Congress. But the fucking Supreme Court let XYZ corporation provide a billion dollars in advertising for a crook named Bernie Madoff running against him, and it totally sunk Joe's campaign. Now Madoff will haul in millions of dollars in bribes from XYZ and a bunch of their crony companies. America the Beautiful!

Get the Citizens United mug.Retard Units is an unofficial synonym for "imperial measurements". As the rest of the world use metrics, the internet culture started mocking the medieval traditions of the Americans, and how little sense the usage of imperials pose compared to metrics.
