2. A term girls who downvote posts on UrbanDictionary call each other because guys call each other “bro” and they want to try to be just like them because “eQuAlItY”

Ew don’t call me that, we’ve known each other for like 3 days.

Si Yang

A weird person who’s emotions can change very quickly, a fun and nice person who is extremely quirky and energetic, though they sometimes can come across as lame. People who have this name can be mean and violent at times but can also be empathetic and extremely kind. (Just be mindful of what you say to them.)

A Si Yang always knows how to bring the energy and craziness.

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.

I’m so Si Ci right putting ma food on da ‘gram
