Resume canyon is a 2024 TikTok phrase describing a long, suspicious gap in your CV from unemployment. "I've got a resume canyon from 2020 to 2022." Self-deprecating job-hunt vocabulary. Not concerning, just career anxiety. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.
