Sierra

Sierra is a really gorgeous person inside and out and will always be there for you. She's insecure and shy but once you get to know her, she'll surprise you with her energy and vibe. She's the absolute cutest and is super smart. If you were to get to know a Sierra, try to keep her in your life. You might even want to marry her.

She doesn't date a lot and probably has a bad experience with having a relationship but if you show her that you genuinely care and love her, she'll probably date you. She has really bad trust issues so try to get to know her so she'll trust you. She's a fragile and precious person that doesn't deserve anything bad so if you know a Sierra, be careful with her.

Sierra likes you for you and won't ever betray or backstab you. You can trust her. She's the best person to talk to at night for those late night "in your feelings" talk. She can read people very well and if you're not careful, you'll fall in love with her. A Sierra's usually depressed but will deny it. Do not forget about how she feels, and keep on asking how she is. This will show to her that you care about her and her well-being.

She's usually a really soft person with hard outer shell from past experience(s) but if you're able to get through her thick skin, you're set for life. The probability of a Sierra being successful in life is actually really high because of their high intelligence and logic. Hang on to a Sierra. You won't regret it.

Guy: Dang man, I think I'm in love with Sierra.
Guy 2: Dang, you too?
Guy: Yeah.
Guy 2: She's perfect.
Guy: True.

Sideræl 

si:`dəræ:L

Sideræl (from Norwegian "side" (side) and "ræl" (scrap, something of low quality). It could be anything of low quality laying on the side, usually worthless.

In 2022, Elon Musk and Grimes named their son "Exa Dark Sideræl". An unfortunate choice since this is not a positive word.

The salad on the kebab plate is just sideræl.
