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.

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!
