Where did the phrase "Da bomb" and the use of the word dog (what up
dog?) as a term for friend come from?
Who started this, yo?
Jerry Lewis in the late 1950's was known to use "da bomb" as a phrase to indicate a rather different cultural situation. Still, its usage has persisted and has taken a slightly different context within the emergence of old skool hip hop culture. As to the usage of "dawg" (not "dog", mind you) I would refer you to that essential reference tool, the _Oxford English Dictionary_.
Other than that, please have a look at http://vr-rottweilers.com/
