Said when someone turns out just like their parent, in looks, attitude, habits, or the same daft little talents. It can be affectionate or a mild dig, depending on what trait you’re clocking. Similar vibe to the acorn not falling far from the oak, but this one’s more everyday and a proper classic.
"Your lad’s a chip off the old block, isn’t he? Turned up late, swore the satnav was wrong, then cremated the burgers and called it smoky flavour. Legend."
