Noun: The upset stomach you may experience when about to see someone that you are twitterpated with (see twitterpated definition if you have not experienced this first-hand). Similar to butterflies, but much more intense and uncomfortable. Usually occurs about 30-60 minutes prior to the date, and diminishes about 30 minutes into the date, if it is going well.
Example of usage: I wish they would sell something over the counter to take for twitterflies, because they are a nuisance and I experience them everytime I am going to see Harold.
