If someone uses BBL slang (https://saferloop.com/what-is-a-bbl-slang/) to mock a child's body or appearance, the child should avoid responding with insults or sharing personal information. They can save evidence of serious or repeated harassment, block the account, and report the content through the platform's safety tools. Children should also tell a trusted adult if the comments make them uncomfortable or threaten their safety. Parents can provide support without blaming the child and help them decide on appropriate next steps.
