Fail Sneeze
When the urge to sneeze is not great enough, the result is a sore nose.
"Why are you holding your nose?" "I just did a fail sneeze."
Sneeze Fail
The epic disappointment felt when you feel the urge to sneeze and it doesn't happen. Especially annoying when someone says "bless you" when you're making the I-have-to-sneeze face and then you can't sneeze.
I hate sneeze fails.
