ballyhoo
To sensationalize or make grand claims.
informal, transitive
Industry has picked up, railroads are carrying more freight, farm prices are better, but I am not going to indulge in issuing proclamations of over-enthusiastic assurance. We cannot ballyhoo ourselves back to prosperity.
Where it comes from
Uncertain. Perhaps a shortening of the Irish village Ballyhooly, known for its rowdiness.
