Kassja is a tough son of a bitch! If you got a Kassja you have a great friend. Kassja always speaks her mind and won't take shit from anyone. She's genuine and gorgeous. Typically Kassjas don't believe they're the best... bUT THEY ARE.

They also are so helpful and sweet, a true friend to all (besides fake hoes).

Kassja's are very intellectual and playful, they are very grammatically correct. They are very sarcastic and will leave you laughing for hours, great company!
