Originally a reference to jewelry made by Daniel Swarovski. Eventually became a term used to describe most Austrian crystal jewelry. An Austrian crystal is the same as a rhinestone, only without a mirrored back. These are high quality synthetic stones made from glass.
A term used to describe the drug "Crystal Meth/Methamphetamine". Sometimes used by drug addicts and drug dealers as Slang, Nickname or Code name to hide it's true identity from law enforcement or other parties. Usually used over the phone.
Since "Swarovski" is a company that specializes in Crystal.
A person who does not understand the word "no", has an predatory personality, and does not know when they are leaning towards a -ism and still "goes for the joke". Overly clingy and tries to sabotage people when their romantic interest likes someone else.
Did you hear about Adam? he was harassing that girl even though she told him no several times. What a fucking Sworski man.
