Acronym which stands for Service Industry Law of Inverse Simping.

Coined by Louis Rossmann, a popular YouTuber and MacBook repairman inside of a taco shop in August 2022, the law posits that since more attractive waitresses generally get paid more in tips from thirsty men, it is society’s duty to tip less attractive waitresses more in order to compensate.
Hey Jim, you should tip that fat, ugly waitress more…SILIS says it’s the right thing to do!
