Sis

A commonly used word, mostly by females. Referring to a close friend or a shortened version of “sister”. Some could say this is “basic” and “overused” by more than half the internet. Someone who would use this word would probably:
1. Watch Shane Dawson
2. Say “tea”, “love that”, “queen” a lot
3. Make jokes about hating themselves
4. Bring up their depression randomly
5. Get into online fights in random discord servers
6. Wear thrift clothes
7. Have “aesthetic” things
8. Be sensitive
9. Feel the need to drink Starbucks even though they don’t like it
10. Wear adidas and giant hoodies
And the list could go on...
“Hey, sis! How are ya?”
“Omg! Spill the tea, sis.”
“I got some tacossss sisss:D”
“Sis, just stop.”
“Sis, you ain’t cool.”
“Hunny, you needa chill, sis...”
“Sis got some issues”
“Finna slap a bish, sis angry>:(“
“Shhh! Sis imma kill you”

Si An

Si an is your typical Asian jokester in class or at work. Whenever he opens his mouth, you will tend to laugh. He might occasionally reuse his joke, but it is useful to have him around.

When you have a Si An, he will stick by your side through thick and thin. So, cherish him.

Under his facade, his insides are burning down. He might have had a history of people laughing at him because of his name. On days when he feels sian, it is easy to cheer him up. He might even make a joke that might make you laugh.

Si An is a wonderful person and once you really lose him, it's quite hard to get him back. Cherish your time with a Si An.
"hahaha, he's so funny,"
"yeah, ikr? such a si an!"
