look up any word, like fleek:

While in the throes of an emotional situation you blert out statements or comments you otherwise would not have.
"Oh am I in trouble, my girlfriend and I were having a fantastic weekend, I got all caught up in it and had an emotional Tourettes moment. Before I knew what I was doing I told her I was in love with her."

or

Brad "Boy, did I screw up. My girlfriend & I were having an intense arguement and the next thing I knew it I had said things I wish I hadn't"

Scott "Dude, you had a case of emotional Tourettes"
