The word originates from old latin meaning large forehead. It is also a common female name in Denmark if your child is adopted or an abort that didn´t work .
The signe is when you're so drunk that you can't even remember your own name. Being unable to do anything else than being silly. Very common in Scandinavia to be Signe.
Signe is the type of person to marry your mom, and become your stepfather. Many people dislike her for it, but she will give you tiny gifts if you behave.
