We don't understand Women: Their "Whatever" "Anything" OR "You Decide"

1. (Whatever)

Men: What should we have for dinner?
Woman: Whatever..
Men: Why don't we have Mexican?
Women: No not Mexican, the last time i got pimples on my face
Men: Alright, why don't we have Szechwan cuisine
Women: Yesterday we ate Szechwan, today too?
Men: Hmm..... I suggest we have seafood
Women: Seafood is not good, I got diarrhea
Men: Then what do you suggest?
Woman : Whatever..

2. (Anything)

Men: So what should we do now?
Women: Anything
Men: How about watching a movie? It's been a long time
Women: Watching movie is no good, it's a waste of time
Men: How about we go for bowling, or some exercises?
Women: Exercise on such a hot day?
Men: Then find a cafe and have a drink
Women: I am off caffeine
Men: Then what do you suggest?
Women: Anything

3. (You decide)

Men: Then do we just go home?
Women: You decide
Men: Let's take the bus, I will accompany you
Women: The bus is dirty and crowded.
Men: OK; we will take a cab
Women: Not worth it... for such a short distance
Men: All right, then we can walk. We can enjoy the weather
Women: I am hungry, can't walk.
Men: Then what do you suggest?
Women: You decide
Men: Let's have dinner first?
Women: Whatever...
Men: What shall we eat?
Women: Anything..
