This is the discount available as a reward for staying faithful to a prostitute. If you frequently visit the same whore, you might be offered a "slut discount" for your loyalty. Very rare, but from time to time it does happen.
Simon: I've been seeing the same prostitute for about 3 months now and last night she said that because I was a regular client, and loyal, I deserved a "slut discount". I now only have to pay £20 for the full works, it used to be £30.
Lee: Thats brilliant, what are you going to do with the money you save?
Simon. Well, its my wife's birthday soon, so I might take her out for a nice meal.
Lee: Your such a romantic, she is lucky to have you.
Simon: Yeah, I know.

Get the Slut Discount mug.
Just like a slut buffet except cheaper.

A person (usually a woman) who will pretty much do anything and everything to her so-called "dates" for a very cheap price.

You can take her on a date to the dollar movies and not buy popcorn, and she will do anything for you.
Gary: "All I did was buy Tina a ring that cost me 50 cents, and she gave me a b.j!"
Josh: Dude, sweet! She's such a discount slut buffet, isn't she?"
