Galch
A Welsh word for cocaine that makes you think you're the king of the world, until you realize you're just the king of a toilet.
'I ate Galch for breakfast. Now I'm arguing with my toaster.'
'He said he'd bring the Galch, and he brought a bottle of wine. That’s the last time I trust him.'
'She’s been on Galch since 9 AM. She thinks she's a queen.'
