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 😘

- 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!
