So I was over at my parents house for dinner with my new husband (we've been happily married for a year and a half) and I overheard my dad talking to my mom and he called me a slut, a whore, and a hoe all because I'm pregnant! Like.. If I'm 24, married, and pregnant then I would expect to be called a slut, would you? Anyway.. Is this normal? Also my mom agreed with him.

I'd assume there to be more behind that...
Did you, mayhaps, do something to make them believe you are betraying your dear husband? Or that the child may not be by him?
Or do you regularily attend swinger parties and the friend of the brother of the wife of a nephew saw you there?
Do you earn your money dancing topless on a pole?
So many questions/options...
Me and my group of friends still often dare each other to things, a tradition that survived from our teenage years, and many of those dares will have overtones that would raise eyebrows. While we KNOW it's nothing serious about it, others may have a different understanding of it...i'd guess it may be a similar case here, with the parents.
Depending on how "conservative" they are, it may be enough to go partying with another male friend while her husband stays at home. *shrug*
Whore.
Perhaps he wanted you to wait a little longer into the marriage to get pregnant? Not sure. Either that, or there's more to the story. But you don't sound like a slut to me.
He's probably just realizing now that you really aren't his little girl anymore. ;)
If no...
Question 2. How did you get pregnant?
If the answer is anything short of the virgin Mary story...
Question 3. Why are you such a whore?
It doesn't sound like it but for what it's worth he sounds rather pathetic to be talking about people like that at his age. He needs to grow up - he's obviously perfect and without fault.
Are you sure you're 24. I think you still may be a bit young in mind at least.
Here's an idea talk to them directly about this!
Pretty sure the REAL issue may be some cold humor between your parents. Unless you know them explicitly sexually speaking?
It actually would be funny for parents to say this together AS A JOKE, and obviously not realizing that you may be eaves dropping on them! They certainly were NOT meaning such a thing whilst having you and your husband over for dinner.
Actually I think its rude of YOU guys to think so ill of your loving parents. Especially when they were being so 'family' to you AT THE TIME.
Time to grow up now, baby coming one day, you big mumma now.
As for the previous insulting replies towards your loving parents, damn kids shoo, go home.
Whore = person who has sex for money. Or, if we're not taking it literally, a slut.
Pregnant = description of a woman carrying a baby, a natural part of female life, and necessary for passing on the parents' genes to the next generation.
Now compare those two, and tell me: how the fuck could anyone think pregnant = whore?
(bonus points: your mom was pregnant with you, right?)
How long were they married before they had their first child? (Not that it should make a shits worth of difference anyway as you are married)
I'm guessing a little of both.
