It’s okay to use ASL slang because it’s not harmless like others, but you need to be careful. Sharing your age, sex, and location with people you don’t know can be dangerous. Always take a moment to think before you reply, and try not to share personal details. Staying safe and keeping your privacy is important. You should also know to use this slang only casually chatting with friends and family and never use it in official emails and other platforms.
