It's not a cause for concern when parents see their child using “MB” in text messages as it's a benign slang term. Most children and teens use it as an easy way to acknowledge a little mistake or apologize on the spot, while talking with friends. However, it is important for parents to be aware of current text-speak jargon to help understand online conversations and digital culture. Frequent open discussion of Internet usage can be more successful than close supervision. Knowing what to look for in slang words, such as “MB” can help parents understand normal online language trends and not worry or overreact.
