went over like a lead balloon

If something went over like a lead balloon it means that it has gone over very badly or failed completely. This is to say that a situation or a possible resolution to a problem did not in fact resolve the situation or problem at all. A lead balloon is never successful and will most likely fail which is where the origin of this idiom comes from. Whenever something fails, whether it is someone trying to win a competition, or a business not going well, someone might say it has gone over like a lead balloon.
