Note: The question in question has been reopened.
The question 'What’s the origin/meaning of “from belt buckle to shoe sole”?' was closed because
Mr Biden consistently gives the origin - his uncle. The absence of any other source indicates that the phrase is part of an idiolect.
As noted in a closure comment subsequently supported by at least three other closers.
The given reason for closing a question asking about origins and meaning of a phrase is prima facie nonsensical, and seems to be trolling the hapless asker, who has, unsurprisingly, not been seen since.
Am I missing something obvious?
