This is a word my friend used when she was wearing a pair of her
mother's boots (which were basically regular shoes with a small heel and that made a noticeable "clacking" sound when walked in.) She told me they weren't "hoochie-mama boots."
Therefore, "hoochie-mama boots" are those knee or thigh-high boots that most
people wear, as opposed to leather/faux-leather shoes or galoshes which are called "boots," regardless of their length.
Also, boots that may or may not be worn by a
prostitute; the term itself is colloquial, and, as such, is used merely as an expression.
