its when u order Chinese, and put a girl in the little basket in the front, open her legs, pull the vagina lips apart(like wings,) and put rice in her hole while she has her period so when they come back out they look like there sweet and sour on them, then make her eat it.
Ryan - "Hey Carrie, that time of the month?"
Carrie - "Yeah, want to order Chinese?"
Ryan - "Sure, make sure you get sweet & sour sauce!"
Carrie - "No need! I'll get Maggie to hook it up with a Wing Lee!"
