Explain Any Technical Jargon in Plain Language

Someone used a word in a meeting. You nodded. You still do not know what it means. This gives you the plain-English version: one sentence, one analogy, under 100 words. You can run it again for the next term they used.

Explain the term {TERM} as if talking to someone who works in a completely different field and has never encountered it before. Give a one-sentence definition first. Then give one concrete, everyday analogy that explains why it matters or how it works. Keep the whole explanation under 100 words.
