I can honestly say that no one I know has ever heard someone say that.
In my pregnancy calendar, it says:
Quote:Watch out for unusual cravings for items such as dirt, laundry startch, or ice chips. The name for these types of cravings is pica which is caused by an iron-deficiency.
 
The only thing I'm craving ...EVERY TIME WE GO OUT.... is chicken fingers.  My husband is embarrassed when we go to a nice Mexican restaurant and then recommend it the next day.  
Me:  Oh we had mexican last night.  I had the best chicken fingers ever.
Or if I have Mexican, I ask them to substitute the beans and rice for french fries with extra honey mustard.  
Hey, I know what I want.
