Get a cassi mug for your dad Günter.
A female who acts a certain way for attention, but always gets the wrong attention. A "Cassi" has syblings with special needs and get more attention than she does...so she will act out in different ways to fill the hole of her emotions.

Very needy, to the point of pushing people away.
gets drunk to deal with feelings of lonliness and acts even crazier.

Her ways of getting the attention she needs usually consist of drinking to the point of vomiting, trying to make out with everyone around her, obsessing over something( a boy, a color, a car...)
"Breanna gets one beer in her and turns into a total Cassi."

"Um, will you please kick that Cassi out of my house? I don't need vomit on my parent's carpet."

Most funny awesome person ever. She is super smart but doesn't like to admit it. She can be tough, but really she's very sweet on the inside! She's a super loyal friend. She doesn't like to dress up very often but she totally rocks the tomboy look. She can make any situation fun with her witty remarks and sarcasm. She is kind of secretive and closed off at times, but she makes an awesome best friend! She loves her family and truly respects her parents, something not found in most people anymore. Did I mention she'd make a great best friend?!
1. Look at that girl.. She's so cool. She must be a Cassie!

2. This girl asked me if I was a Cassie and I said "Hell no I'm not that smart!"

3. My little brother was backstabbed by his best friend, so he shouted to him, "You're not so Cassie after all!"

Beautiful, but they never admit it. They are very vulnerable, and they fall into peer-pressure often. Sweet, but they can be mean if provoked. Most tend to fall in love with the wrong people, and are very flirtacious. Their laughs are amazing, and they give great hugs.
Awe she's really cool. She must be a Cassie!

A wonderful person to be around. All around Cassie's are smart, beautiful, funny and loyal. Although she may seem shy at first, she will open up and show you her amazing personality. Cassie's make VERY good friends. They are loyal, very forgiving, protective and easy to talk to. Although some people dont realize how great Cassie's really can be. She often has GORGEOUS green eyes! If you know anyone named Cassie, I would get to know her! She will be the BEST friend and or girlfriend you will ever have gaurenteed :)
