The sausage scale is the scale you must look at when defining if an event is a sausage even.

A sausage event occurs when the

male population > female population

If the male population represents:

=50%: Supper
>50-59%: Sausage snack
>60-69%: Sausage cocktail
>70-79%: Sausage fest aka SF
>80-89%: Sausage buffet
>90-99%: Sausage banquet
=100%: All you can eat sausage

The same scale applies to woman, but the word donut is used. (merci sam)
