The act of making love to an asian woman from behind in the rectum, and as the woman turns around you realize she has a penis.  85% of the time a donkey punch will result.
Last time I was givin' it to Sook Yin Lee in the ass she spun around and gave me a shanghai surprise!  I'm not going back to china.

Get the shanghai surprisemug. During Sexual intercourse from behind, the penis is withdrawn, the male spits on his partners back, and begins to vigourously masterbate, and when his partner turns around, he ejaculates in her face.

Get the shanghai surprisemug. Come on. Everyone knows that a Shanghai Surprise is when you take a shit in someone's toilet and instead of flushing, you just put the cover down. When the next person lift the cover to use the toilet, there is a nice shit waiting for them.

Get the Shanghai Surprisemug. Long before George Harrison, Sean Penn and Madonna and the movie they made by that name, a Shanghai Surprise was a home made bomb used by the Chinese tongs or gangs. The expression probably dates from the late 19th or early 20th century. While I cannot cite chapter and verse of it's origin, I'm older than Madonna and understood the expression at the time the movie was made. Not everything is about sex, kids. That's why I unsubscribed from the UD.
