A Zaggy is a girl u see with a nice body and uglyfast or nice face and ugly body. For males it is called Zagger
For example you see a girl and they have some nice boobs and booty but then u look at her face an it looks like a horse kicked her in it so u go "DAM Zaggy" or "look at that Zaggy". Or u see a girl with a hot face and the u look at her body and shes fat, thin, small breasts, no ass, ect. And the same thing goes for Zaggers.
An alter-ego created by David Bowie. This character was featured in his 1972 album titled "The Rise and Fall of Ziggy Stardust and the Spiders From Mars". This character was what helped Bowie get started into the music industry, from Ziggy's odd costumes, featuring unearthly colors and different types of shine, to Ziggy's eccentrics. Ziggy was a guitar-playing, bisexual, alien who fell to earth to share his music.
