One day, a student liked the word "bottakuri" very much. Do you know what "bottakuri" means? If a taxi driver charge a exesssively expensive fee when the passenger doesn't know the way, it is a bottakuri-taxi (That is quite rare in Japan). If you go to a bar and if they charge you ten thousand yen (=100 US dollars) just because a pretty female employee of the bar took a seat next to you, you can call it a bottakuri-bar (That might happen. Be careful). If you cook Takoyaki at home, one ball costs only around 10yen (=10 US cents). If you find that a plate of 8 Takoyaki is sold for 1,000yen, that is also bottakuri!
