A word originating in Lancaster, California meaning a cheap, masculine, hermaphroditic prostitute dressed as a woman.
It is commonly used as an insult or a means to describe anyone/ anything similar to a tostiprute such as a very ugly whore, a transvestite prostiture (for which the proper term is trostipute), an excedingly masculine woman, etc. rather than its official meaning.
Kevin took that five dollars and bought himself a tostiprute!
Man, she looks like a frikkin tostiprute!
