gansociego
A scam or a dud, specifically an object that looks flashy or valuable but turns out to be poor quality, broken, or a total deception. It is used when reality falls far short of expectations (paquete chileno refers to a classic street scam where a bundle of paper is disguised as a roll of cash).
(El Zarco looking at the water-logged watch he stole from Monica, from the movie The Rose Seller.) That bitch fucked me over with this gansociego, man, I am such a damn fool, she can go eat shit.
