A substace so terrible that it's creators should be murdered, or worse, forced to drink it themselves.
Used for cruel games of truth - dare
Also used for cheap stomach pumpings
Example: 1. I dare you to drink this Malta Goya
2. I'ld rather impale myself on a fencepost like James did!
Example: 1. Dude! you just drank petrol
2. Woops, better get the malta goya out
