How to remove trendy speech from llms?

For example: Instead of saying: "I created this new ID" It says: "I minted this new ID" Instead of: "This alternative path is available" It says: "this escape hatch is available" This speech is so nonsensical and annoying. Just. Speek. Literally ... OR NORMALLY. Where did LLMs learn these speech patterns? I've never seen them so frequently until AFTER the LLM surge. If I just add "Don't use X language, speak normally and more literal" will that fix most of the issues? Anyone else have some good sys prompts / instructions that help with this? Thanks!
