Sienna

A girl who gives mixed signals. You probably will like her, but if you make the first impression bad, you will regret it later on.

YOU WILL NEVER RECOVER, be careful buddy. She a true hottie tho!
Me - *makes inappropiate joke to friend (not intended to her) while she is around*
Friend - *laughs*, "Yes, that was actually funny my guy fr.
Her - *disgusted or weirded out in someway*

IT WILL TAKE A LONG TIME TO RECOVER IF U LIKE HER OR SOMEONE NAMED SIENNA!

Sienna

She will surprise you. Often siennas are like mirrors. You see one thing and then another. She is nice then mean and also sometimes will have boyfriends that last a day or two, maximum. Otherwise excellent.
Sienna is cool sometimes.

Sienna Syndrome

Sienna Syndrome is a type of syndrome where you have a crush on a girl. Once you do, you forget she is in your presence and start acting goofy, inappropriate (as a joke), and weird in front of your friends which makes you laugh. Your crush gets weirded out and there is never a chance for a second impression, though you can still come close to her if you are somewhat of her type and improve. Not guaranteed though. Men, be careful! It may be uncurable if you aren't careful and do it for long periods of time without knowing she doesn't like you for a while.
Me: *acts weird in front of friends and makes them laugh and say something just as weird back*
Crush: -in the distance- Wow, he is kind of weird. I'm going to try and avoid him.

3 MONTHS LATER...

Me: Hey -----!
Crush: Oh it's him.. Hi.
Me: *walks away* How can I make her mine?? It is so weird how she is acting
GOD: The irony is crazy! >:) He definitely has Sienna Syndrome.
