Yawei - aka the chinese penis trap. When you get your penis stuck inside of a sideways vagina. There have been 6 reported penis amputations of this disorder.
I was banging this prostitute, who's name I thought was Yawei. Little did I know, she was just telling me her specialty. She compltely yawei'd my penis and I was stuck for like 4 hours.
