Guy: "Hey man, I picked up a case of Goose Island 312 Urban Wheat."
Dude: "Di-fucking-sgusting."
Guy: "What? I thought you liked that beer."
Dude: "Psssht, maybe in 2009. Ever since AB-InBev bought them that beer is straight-up dilly."
A tablet of Dilaudid® a strong analgaesic (hydromorphone hydrochloride 1, 2, 3, 4, or 8 mg) derived from morphine and invented in Germany in 1926; it is eight times stronger than morphine via the intravenous route and therefore marginally stronger than heroin.
I finally got relief from the injury after the doctor switched me from Vicodin to some 3 mg Dillies.
