BrainyBabe The main use in British English is to describe a semi-detached house, often of Tudorbethan style. Sandi Toksvig, a BBC presenter of multiple talents, came out of the closet in the mid-1990s, and was dropped like a hot potato by Save the Children, for whom she acted as a sort of ambassador. She exploited this to comedic effect in a stand-up routine, in which she recounted her mother's reaction to the whole hullabaloo: "It's terrible what they said about you in the press! I just can't believe it. They called your house a semi!" Dec 25, 2008
