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.
