When you feel like you are about to
sneeze, but the urge disappears when you are
already halfway into it. These types of sneezes are not as satisfying as
regular sneezes, and often result in embarrassment and/or receipt of the "wtf" look.
I was in class when I made an aborted
sneeze. I had tried to hold it
back, but it came out anyway. Rather than sounding like "ACHOO", it sounded more like "ACHoasdfgh". After it happened, I just sat there and hung my head in
shame.
