In the world of
espionage,
the romeo is a male who is carefully placed within a high level government agency to seduce lonely females placed high in the government,and use emotional and/or romantic blackmail to gain sensitive information about
the government's activities.
Females also were used in this capacity during the cold war, and were thus called romiettes.
The
Warsaw Pact intelligence agencies routinely placed
romeos into western governments to engage in
subversive activities and influence.
