It’s interesting that the translation can change as soon as the noun is used as an adjective.

“Schlampe” = slut, always an insult (if not some kind of dirty talk).

“Schlampig” = sloppy or slutty, depending on the context.

In German, only the adjective has a dual meaning: “not neat, untidy, messy, or poorly made/done without proper care.”

If one wants to apply the other meanings of the adjective back to the noun, however, one must alter the word, so that “Schlampe” becomes “Schlamperei,” which in turn is the result of actions that can be described by the adjective: The product of sloppy work is “Schlamperei.”

German really is a bitch…
