A jack of all trades who is loyal to her friends, a person who can be trusted but not one to be crossed. She is known for her quick wit, sharp tongue, and love for the word "cunt".

Many people love a Carstine because of the fact that she is a good friend, and many hate her for the fact that she doesn't take shit from anyone.

It's rumored that while she downplays her own attractiveness, a Carstine is a fine example of a curvy woman; large breasts, round ass, and a little extra meat to grab hold of due to her
Don't go crossing her. She's nothing short of a Carstine...
