Si Ci

Si Ci is an absolute legend. Her ability to instagram copious amounts of food (on the hour, every hour) while simultaneously completing intensive study makes you feel like an under achiever for sure.

Not only is she a restaurant/eatery connoisseur but Si Ci is an Ultimate frisbee superstar. While her mad throwing skills & defensive prowess make her a teammate’s favourite; the thing her team loves about her the most is how she laughs at everyone’s jokes making them feel hilarious.

Luckily she has no plans to leave us. Ever.

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”
