Boo stands for Booty. Men have changed the meaning so their "woman" would not be offended by having the name booty. Women do not enjoy being labeled as property and men are much smarter than people think

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.
