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
