Get the Junkie's lawmug. A mother in law is pretty much the very bane of your existence.
A mother in law (or MIL) is a wretched, treacherous female. She is insecure, jealous, petty, hateful and filled with spite. She is immature to the max.
She is shallow, empty headed and only cares about appearances. She is a master manipulator, and a huge control freak. She has to be in charge of everything.
It does not matter if the child(ren) she bore are in their 30s, 40s, 50s or 60s. She still must be a heavy influence in their lives, and she cannot exist without knowing their Every. Single. Move. She gushes unsolicited advice and is not satisfied unless she pushes her dumbass opinions. She HAS to be the center of attention. She is backbiting, hypocritical, sneaky and mean.
She pretends at church, pretends with the neighbors, pretends with the bridge club, but she is a fake, through and through.
She will constantly berate you, berate others, poke fun at people, make nasty comments behind your back, and betray you and others by gossiping about your/their private business.
A mother in law is a bitch from the bowels of hell.
A mother in law sometimes giggles like an evil 7 year old. She laughs at her own cruel jokes, with her long, yellow, scary teeth.

Get the Mother In Lawmug. 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
