Sinisha 

Derived from the Serbo-Croatian word for son, Sinisha is the name of a cool guy. He may be a bit angry at times and maybe a bit rude but you can trust Sinisha to pull through even if things aren't going too great.

Person 1: "Damn, why is that guy so mad?"
Person 2: "Just give him time. He's a Sinisha."

Tracie Sinidol

Sabah-born Malaysian actress who is well-known for her face that really looks like Mira Filzah. She has become so popular with "Luruhnya Bunga Cinta" that is based on a K-Drama titled "Autumn In My Heart".

Many people call her "Nuha" due to her role as Nuha in the drama. Of course, it's not her real name. If the drama ends, you guys just need to call her "Sinidol".

Alif: Zam, tengok sana! (Zam, look at there!)
Zam: Aik, itu bukan Tracie Sinidol ke? (Oh, isn't her Tracie Sinidol?)
Alif: Ye lah! SINIdol ada kat SINI!🤣 (Yes! SINIdol is here!)
