Ok, it took a while with the stupid dictionary, but I got it!:
whore: a prostitute
prostitue: a person, typically a woman, who engages in sexual activity for payment
slut: a slovenly or promiscuous woman.
slovenly: messy, dirty, casual, and careless person
promiscuous: having many sexual relationships, esp. transient ones
transient: lasting only for a short time
I usually like big words, but that just got irritating.
