What is a wormhole slang?

Excuse me, could you please clarify something for me? I've heard the term "wormhole slang" mentioned in a few conversations recently, and I'm not quite sure what it means. Is it related to some sort of technology or perhaps a specific subculture? Could you provide a brief explanation of what a wormhole slang is, and maybe give an example or two to help me understand better? I'm really curious to know more about this term and how it's used in different contexts. Thank you in advance for your help!
