If you are talking about a runny yolk that you can dip bread into, I always order mine 'over easy' or 'over medium' (egg is fried on both sides). Also you can get them soft boiled and the yolk will run. "Sunny Side Up" is another term for the runny yolk where they fry the egg only on one side. I love runny yolks with rye bread for dipping.
