An American business man flies to Japan for some business meetings and a few rounds of golf, arrived in Tokyo a day earlier than expected.
That evening, he meets a cute Japanese woman at a the bar of his hotel, and after some drinking and miming, she agrees to go back to the room with him for some private fun. Their passion qickly became intense and in the heat of the moment the Japanese woman began yelling "Gama Su!, Gama Su!" Knowing he pleased her greatly, the man was very pleased with himself and went to sleep.
The next day while playing golf with his Japanese business colleagues, he made a swing when suddenly one of the other guys started yelling at him "Gama Su! Gama Su!"
The bewildered American asked: "What does that mean, Gama Su?"
