Boo is right, I do not look cool when i use these words, I only use them to wind my daughter up.
I enjoyed following and seeing bands like De la Soul, Cypress Hill back in the 90's, the only rap act that i have in my collection after that are J5. Tupac and Biggy etc passed me by as i found dance music and the two genres are polar opposites. Rap being quite fierce and sometimes with a violent message whilst dance being about arms in the air and everyone smiling.
Most of the audience here are not your demographic, you would be better off asking the people here about slang and terms they got from their music, how it effected their life and compare that with what you think about rap music. Music from each generation provides its own slang, go back to the 50's for words like hip, hipster etc, words that are still used today, there are others that are not used, "hey daddy o check out that finger zinger" for example. :) Will this be the same for rap?
Rap has not as far as i am aware been a major influence in how i communicate with my family and work colleagues but in a social environment it has had an impact, maybe more the way words are said than the words them self, maybe i am talking about swagger. (See, there is proof!)
Anyhoo, great question.
