boo 

A truncation of the term "boojum" used in the movie "Rally 'Round the Flag, Boys!"which was based on the very humorous novel by Max Shulman. In the novel, Max used the word poontang shortened to poon. In 1958, poontang was not acceptable on screen; thus the substitute word boojum which had no prior meaninng and thus seemed neutral.

Army Private: "When we get to town, I'm gonna get me some Boo."
