Chi Chi derives from the Jamaican patwa for termites or cockroaches due to the sound they make at night. This then became a term to describe parasites which then became an insult as the people of Jamaica were calling police and politicians chi chi men, doesnt really mean gay people but it depends on how you look at them.
