“Menty b” is a slang term signifying a “mental breakdown,” according to Know Your Meme, a website defining memes and other viral content. It’s often used to describe an overwhelming feeling or when someone is experiencing stress over something.
The term has gone viral on social media with some videos on the topic racking up millions of views. Using the term is not necessarily indicative of an actual mental breakdown, nor does it taunt people who are experiencing one. Some feel it's bringing more attention to mental health issues, which have been on the rise for teens. But not everyone is a fan of the term. Yet, it's important for parents to pay attention.
