Roblox Glossary: 60 Terms Every New Player (and Parent) Should Know

How to use this with your kids

• Ask them to teach you. Kids love explaining “W/F/L”, and you’ll learn how they play.
• Watch for the risky words. “Trust trade”, “script”, “free Robux” and “admin” are your cue to check in.
• Check the settings together. My parental controls guide covers spending limits, chat and who they can connect with.
