Actually "whore" is equivalent with the word hooker. The word hooker is fabled to have originated in the United States around the time of the civil war. The word was given to whores (prostitutes) that would frequent Maj. Gen. Joseph Hooker's encampment, although there are arguments against this case, some of which actually seem to disprove the word Hooker coming from the Generals name it is still true that the word originated in the United States as the earliest use of the word, were in the meaning is prostitute, are found in the North Eastern States. Therefore Whore is infact a prostitute or a hooker. A slut is the word you are looking for, not a whore. A slut is a promiscuous woman, a female dog (a synonym of the word bitch), a chiligrrrl, a bitch who sleeps around, eats more cum in a day than both my balls can produce in a year, makes phone calls to D-sane and gets shit posted about them online.
Edit: That guy erased his post! So this will make no sense now.
