A "long bomb" home run as first described by Atlanta Braves career player and third baseman Chipper Jones (#10). Mammo is sometimes associated with the term "yicketty" which is a general term for a homerun coined around the same time. Both terms were made popular by the Chipper Jones tweet: (see example)
Chipper Jones: "Mike b and jhey go yicketty! The roadrunner went mammo! And the Bravos have a winning road trip. My kind of day off, no action!!!”
