A slut is somebody (usually a woman) who has lots of sex. They are not
necessarily bad, as they help people achieve the stimulation they need, without raping
innocent people.
(A slut is somebody who has had sex with at least 10 different partners within a short space of time, or somebody who has sex
all the time.)
Don't use this as an insult, use "Omnimoronic hyperbole" instead. PEOPLE WHO CONSTANTLY USE THIS AS AN INSULT ARE sexist
