TRAP has it's orgin as a Georgia term for that "spot" where NICCAZ sell everything from moonshine to white tees, bootleg dvd's to crack....
i know because i use to frequent a TRAP down in savannah georgia....
where you got roger wood sausages being cooked right thier on a grill for a low country boil with some golden grain alcohal, while some high grade was being served to the traffic passing thru...
you are only familiar with it because of the RAPPERS who sensationalized the most significant characteristic of a TRAP which is COCAINE.....
But keep in mind the TRAP been around long before your ATL favorite rapper started promoting it....
