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”

Sis

A acronym for "she is self".

Look at her, sis is beautiful. Which means when you speak of Sis, Sis is yourself. It speaks on how you think and feel of yourself. Positive or negative. Talk to her nice 😘

Lao Si Ji

Lǎo sī jī (Old driver) 老司機— Chinese slang for someone who’s way too good at ‘driving’ — and by driving, we mean knowing a lot about sex, porn, hentai, lewd, and adult content.

- Oh man, didn't know you watch so much porn! You are a Lao Si Ji.
- Nah, Tom is the real Lao Si Ji. He is into hentai anime and stuff.

William: Are you doing your homework?
Ray: No.
William: What are you doing then?
Ray: Your mom.
Crowd: Ohhhh.
Kevin: Yo, Ray drives fast!

SI

Means self insert. The character you use and identify yourself to have sex with your anime waifu.

-I'm going to write a fanfiction between my SI, Jackard Bigchub Maximus, and Sagiri-chan.
+Do it elsewhere. Disgusting.

sis faz favor

Female (and feminist) version of "bro favor", from the Portuguese "se faz favor" (please). Means "do a girl a favour" in the spirit of "Sisters Are Doing It For Themselves".

"Sis faz favor, tell this weirdo I'm a cop, so he'll stop following me around".
