The term "boom boom" is most often associated with south east asian countries such as Thailand, Cambodia, or Laos and is used to describe the act of intercourse, usually that which is purchased by males frequenting brothels and whorehouses in those locations. The term is thought to have been created by prostitutes possessing limited english language ability; ie- it is far easier for a non english speaking Thai prostitute to say "You go boom boom"? than it is for her to say "Would you like to go make completely unemotional and detached love with me"?
