When a "woman" unexpectedly reveals that she is, in fact, a man and has a penis. It is called a Thai surprise due to the extra convincing look of Thai men posing as women.
I got back to my place with that Asian girl from the bar and she gave me the Thai surprise, I'm pretty sure her penis was just as big as mine.

An unexpected, dramatic last-minute event which potentially alters the outcome of an election. The term dates to the 1980 presidential campaign, in which Jimmy Carter planned, for October of that year, an operation to rescue American hostages held in Iran. Carter was lagging behind in polls and a successful rescue, an "October surprise," would likely have shifted the momentum to his side. The attempt failed, however, and Carter lost the election. Some have suggested that the Reagan campaign deliberately sabotaged the effort in order to bolster his candidacy.
Before Osama bin Laden released his newest tape, some people thought the Bush campaign would produce him as an October surprise.

Common mostly with females, a surprise poo occurs when you go to the toilet to have a piss but end up following through- fortunately on the toilet- as you were unaware of your bowel evacuating needs.
Uncommon with males as they pee standing up.
