Where in the hell did they get the word kamehameha? Don't you ever wonder about that. I'll tell you one thing Akira Toriyama did not make that word up. I went to hawaii on vacation with my family and cousins. As I was walking around, I saw a big statue with the writing King Kamehameha on it.
King Kamehameha was a ruler of the island of Hawaii in 1782 and by 1810, through conquest and cession, had united all the Hawaiian islands under his rule. He was considered the greatest king of Hawaii.
