Sung-ki

Sung-ki or Sseong-gi is a Korean given name. It was the ninth-most-popular name for newborn boys in 1940, according to South Korean government data.
The name is not commonly given to babies with the family name Nam, as the resulting name "Nam Sung-ki" is a homograph and homophone of the Korean word for penis. The 2005 Seoul Broadcasting System television series Hello My Teacher was criticised for its inclusion of a character with the gag name Nam Sung-ki, for this reason; some commentators believed this penis joke was inappropriate for television.
