Very fast. Similar to the speed that my father had when going to the store to get milk. It's only beaten by the speed of a fast red car from some movie...
"Where'd dad go??"
"He went to the store to get milk"
"But I didn't even get to say goodbye..."
"I know... Gheto Speed..."
While living in the ghetto you cannot afford good dsl or cable speed so you resort to hooking up a sort of hamster wheel where ghetto rats constantly run on (high on crack of course), to power your internet.
I know that homie from Cherry Hill must of had ghettospeed internet, because his black ass was lagging like a mutha fukka on NBA 2k7.
