siedah 

An amazing girl who blows you away every time you look at her. A Siedah has gorgeous eyes that you can stare into for days and a body that'll kill every guy she walks by. A Siedah loves to have fun and is very relaxed in relationships and try to at least give everybody a chance, or make it seem like theres a chance. Though a Siedah can start out on the shy side, once she opens up to you she'll never shut up, which is a blessing and a curse. Usually very relaxed and easygoing, Siedah's know how to have fun though sometimes they can take it too far. A majority of Siedah's can't stand shopping or any type of retail therapy and prefer to eat. Siedah's are incredibly chill, sometime to the point where they look bored.

Guy 1: Hey, dude, that girl is a Siedah
Guy 2: Damn, she's cute

FDS SIMÃO 

What you say in Portuguese when someone does shit. If translated literally it means something like "Fuck you Simon".
Simão was a famous Portuguese student of the renowned NOVA University of Lisbon that nobody ever understood how he managed to enter to such a reputed institution.

In the meanwhile, the expression has spread nationally and is now used in a wide range of contexts.

*Person 1*: "Dude, I missed all the classes in the last 3 months. Can I have your notes, please?"
*Person 2*: "FDS SIMÃO"

Sima 

Sima is a great friend. She is a badass. she doesn't take other people's shit. At first, she can seem a bit intimidating but if you manage to see past that and become her friend she will protect you. She is athletic and has a reputation for beating up boys from her neighborhood. She has a dark sense of humor. She is a straight-A student. She loves blood. She is gorgeous but doesn't always feel like it. She is the friend you go to for relationship advice even though she hasn't been in a relationship. She has most likely stalked you. She loves the dark web and scamming scammers and loves hacking.

So basically she is a great friend but can be scary. She is smart and beutifull.

Sima is the type of friend i want.

Sidah 

When you first met her you thought she would be unapproachable because she looks not so friendly. Later you realize that she's just shy and actually a very kind person. So popular, gorgeous, cute and grace. Got many fans and friends. Hardly loves someone and believe people. But don't get fooled by her beautiful appearance. She's actually a good liar and her words can make you trigerred for real. Her eyebrows are so idol and her lips is pink as a sakura flowers! Boys got no chance to know her unless she wants to get know them first. She's weak but try her best to be strong. Can't hide her feelings, it's all written in her face. After all sidah is a very unique person and you will find it interesting to get know her

Person 1: Ugh, I hate Sidah! She's acting all kind but she's not an angle!

Person 2: Of course. Duhh, she's an idol! Look at her,so damn cute

simant 

A simant loves boobs. He is the most nastiest person you’ll ever get to know, but in a good way. A simant doesn’t easily get attached to things but when he does, he’ll love you unconditionally. A simant is a guy who minds his own businesses and literally gives no shit about what people think. He will never show you who he really is until he trusts you, so never judge a simant if you don’t really know him because his awkwardness might be mistaken for something else. A simant is also very selfish, but when it comes to relationships that means he will give you all his attention and want you all to himself. Also, if you ever get to be close to a simant he will always make you feel like you can be yourself. Don’t ever let a simant go because he is really one of a kind.

guy 1: who is that guy? he’s so cool.
guy 2: Bro that my man simant.
