There's 31 years separating the eldest millennials from the youngest of Gen Z - but there may as well be an ocean between them. Last month, American singer-songwriter Allegra Miles went viral on TikTok when she compared popular millennial slang with its Gen Z equivalent.   The 21-year-old said terms like 'YOLO', 'game', 'slay', 'on point' and 'vibe' - which were all popularised by millennials - have now been replaced by cooler Gen Z slang. In recent years, the sparring generations have warred over everything from the 'most flattering' style of jean to the 'correct' way to part hair. Here FEMAIL reveals the key issues that divide Gen Z and millennials - from their favourite sock style to their nail shape.
