The "halitosis bomb" and "gay bomb" are informal names for two theoretical non-lethal psychochemical weapons that a United States Air Force research laboratory speculated about producing; the theories involve discharging female sex pheromones over enemy forces in order to make them sexually attracted to each other.
In 1994 the Wright Laboratory in Ohio, a predecessor to today's United States Air Force Research Laboratory, produced a three-page proposal on a variety of possible nonlethal chemical weapons, which was later obtained by the Sunshine Project through a Freedom of Information Act request.
