When someone in a crowded room sneezes, and another person sneezes no more than 5 minutes later. This is the essence of the sympathy sneeze. Also, when a loud, spit-flying sneeze is let off in an extremely quiet room, some caring person may choose to fake a sneeze just as loud in order to minimalize embarassment.
Kid: Did you hear Jill sneeze in the middle of the SAT's?
Other Kid: Yeah, I let off a sympathy sneeze, just to be nice.

I was eating a tuna sandwich while driving one day, and I felt a sneeze coming on but I couldn't chew and swallow fast enough - Tuna Sneeze all over my windshield! Yuk! (True story)

A girl that sneezes, but does it in such a way as to sound feminine, so as to still be "attractive" to the boys. Instead of the deep, loud kind, it comes out high pitched and squeeky, dainty if you will.
