As the use of the word "zauche" is meant to be "offensive"
...the word's meanings, here, are more like "cunt" (for "bitch") and "slut/whore" (for "dissolute woman")

In older or dialectal German usage, "zauche" can be a derogatory term meaning “bitch” or “dissolute woman”.
This usage is considered outdated and offensive, and it’s not commonly used in modern German.
