Riff Raff lyrics

"gangster/thug or some who is out to just having fun for example 50 cent"

Bless the internet for giving a 12 year old a voice but, that is retarded.
I can't be certain but, i'm pretty sure it's not about selling crack and getting shot with your homies.

Think more like getting out of the auto/cnc/steel/ whatever factory after 10 hours and stopping at the closest bar; beer, shots, pool, pinching the waitresses asses... Broken beer bottles and, loud ass rock. Problems were dealt with punches one on one, and it was over. It was rowdy, certainly not the animal unevolved crap that goes on today.

I remember times like these, with my father at the bar. And i've had a few wonderful memories of my own but, somehow people became weak and a gang mentality took over. Lame.
Pride and joy of '77

I think it is a type of gangster/thug or some who is out to just having fun for example 50 cent
