Talk:know one's ass from a hole in the ground

This has no meaning
It's not that it is "frequently" used in the negative. It only has any meaning in the negative, such that the entry should be at.

To the limited extent any of its synonyms ever appear in the positive, it's as the negation of the base accusation of not being able to distinguish these things. — LlywelynII  03:42, 12 March 2023 (UTC)
