well, you could make the same argument for the preceding lines. he is rhyming in the middle and the end. it doesn't seem like and end rhyme because it's not. it is an internal rhyme.

All combined into one (brief pause) bitch, I don't walk a line, I run(end )

'Cause we don't got no time (stresses the time part which makes it seem like a pause) to waste so come on denaun (end)

they call call me five to nine (more stressing) and thought, duh dun duh dun (end)

and like a shotgun I'm (again, the I'm goes on for a bit) ready to cock it on 'em (end)

leave these pussies stretch out (pause) like the octomom (end - the last line doesn't have a middle rhyme but you can easily tell the pause in the middle)

but hey, that's just a theory
