Hilwa means sweet and beautiful. It comes from Arabic which is Halwa. She is a cheerful person, but when she is alone she cries. Give her a hug. She knows everything and can read what's in your head. If you are nice to her, then she is too, and vice versa. She always tries her best for those around her regardless of herself. Achieve what she wants without having to bother others.
My sister came up with this word to describe me when she was about eight years old. It is a portmanteau combining "hilarious" and "comedian." It is used sarcastically conveying the idea that "although you think you're funny, you're not."
Dude: Jack be not nimble; Jack be not quick; Jack couldn't jump over that therecandlestick.
Bro: Hilarious, dude.
Dude: I'm a poet, I knows it.
Bro: Yeah, you're a real hilarian.
