First used in early 2009 in Victoria, Australia, this term is commonly used as a colloquial term in both a descriptive and derogatory fashion.

Noun - To describe a person that shows a distinct lack of moral fibre and/or moral scruples. A person that acts selfishly, with or without any thought, towards a person or persons towards whom they should demonstrate respect, grattitude, or ethcial consideration towards.

Adjective- An act that is performed by one person towards another person, often causing tremendous disadvantage to the affected party, and is performed to provide the perpetrator with some type of gain or advantage.
SIDNEY is a term that can be used in the same fashion as, and in place of, the term Judas.

"I got that bitch a job, a house, lent him money, and then she pulled a SIDNEY on me. She took my job, screwed my husband, and kicked my dog. What a cock smoker!"

"I cant believe he chucked a SIDNEY on me! After all I have done for that guy he really stabbed me in the back..."

"Mate, I really need your support on this right now. If I bring you in on this project you better make sure you don't rip me SIDNEY style, or I will be forced to kick your ass!"

"I can't believe my bastard husband! He left me with a young child, no money, took the car, and was fucking my best friend behind my back...he really handed me the big SIDNEY, and I don't know what to do."

"You treacherous, SIDNEY-ass motherfucker."
