Kids are saying certain repetitive slang phrases, like "six seven," mainly because they find them fun and amusing to say. These phrases often have catchy rhythms or sounds that kids enjoy repeating endlessly, sometimes out of context or just for play. Such repetitive language use is a normal part of language development and social bonding among children. The specific phrase "six seven" became popular through internet memes and a viral rap song, and it has no particular meaning—it is used more to engage with trends and connect with peers than to communicate a clear message.
Children mimic what they hear in media and from each other, and the rise of social media platforms like TikTok rapidly spreads these phrases. Repeating slang can also be a way for kids to self-express, entertain themselves, or get reactions from adults, rather than trying to annoy or communicate specifically. While sometimes such repetition links to neurological behaviors like stimming or echolalia, in most cases, it is harmless and part of typical childhood exploration of language.
In summary, kids say these kinds of phrases because they are fun, socially engaging, and part of natural language play and development amplified by modern digital culture.
