Meaning
Literally, “They work in the gear.” In everyday French it means that a group is busy working on or with the equipment – for example in a workshop, a recording studio, or on a construction site. The verb *bosser* is informal, and *matos* is slang, so the whole sentence carries a casual tone.
When to use
Use this sentence in informal conversations with friends, colleagues, or fellow hobbyists when you want to comment on people being occupied with equipment. It’s perfect for a relaxed workplace chat, a music‑production forum, or a sports‑gear discussion, but avoid it in formal reports or academic writing.
