Ghetto Blastro
From Homestar Runner Wiki
The Ghetto Blastro is combination radio/tape player that first appears when Coach Z uses it to learn how to say the word "job" correctly. Strong Bad uses it at his party in The Luau to play all the latest releases of the artists of today.
Various versions of this device, identifiable by such features as the oversize speakers or the LED equalizer, have appeared including a Puppet Time and Powered by The Cheat incarnation.
The Brothers Strong own a piece of equipment similar to it, called the booOOMbox.
As far as origins, "Ghetto Blaster" is a generic '80s term for a boom box, so named because of the proliferation of bass-filled rap music at the time and the usage of the word "ghetto" to describe the inner-city homes of many rappers. It was also the finishing move of a WWF wrestler named Bad News Brown (aka Bad News Allen).
