A slang term to refer to LSD (lysergic acid diethylamide). The term "Cidney" derives from word "acid" which is another term for LSD.

Cidney is often used as a code word for LSD when referring to the drug in a public setting or over the phone where one does not want to openly discuss illegal activities.

Cidney is used like a person's name in such discussions. Like saying "I'm chillin' with my cousin Cidney this weekend" to indicate you are planning to use LSD over the weekend.
