Dirty South Duplets

I was reading the New Yorker today and came across this description of Lil' Wayne's rapping technique. Only they could describe his dirty south rap style in such a manner:

"Lil' Wayne chants, relying on combinations of tart duplets and sixteenth notes to deliver his boasts."

Here's one of those boasts from "Ask Them Hoes":

I dont know why you love her
I wish I never knew her
She only give me brain
She was just another tutor
She blow my whole band
I was just another tuba
Now get off my dick
And get lost in aruba

Wow... tuba/aruba...nice...I haven't heard a tarter rhyme in ages...
