SILIS

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!

Sigismund

Sigismund is a word used to define the most cooked member of a friends group. If there are multiple you would define them as "Sigismund 1, Sigismund 2, Sigismund 3..." and so on. One becomes a Sigismund by:

1. Being Brainrotted
2. Being the lowest scorer in tests
3. Playing world of tanks blitz and considering it fun
4. Disliking the witcher 3

Oh and theres Sigismund 1, great. Time for him to rant about 67 and Italian brainrot for another few hours
