Hot Asian Alert
When a non-Asian male see's a very attractive female Asian in a public setting, he can then give the "hot Asian alert" to his male companions. This usually consists of a "beew beew beew beew beew" type of noise, and the twirling of the pointer finger in the air. His friends will then know they need to take a gander.
Me and the guys were in a Parisians when Paul spotted an attractive asian woman. He quickly gave the "hot asian alert", and the rest of the guys were quite impressed. Paul was accepted socially for the next couple of days.
