I had no idea this was so naughty: there's a doodle in my noodle and it's name is minky boodle! :eek
I was never taught to call it anything really...but we started naming it silly things when I was in college. Par example: va jay jay, bajingo, hey naner naner, sissy, lady business, hoo ha, tuna taco, etc. No foo foo though...which is funny because little bunny foo foo hopping through the forest ALSO takes on a whole 'nother meaning.
