I was lead to this from rockstargames.com:
http://www.rhymerator.com/base.html
It's pretty much an aid for poetry, but with a rapper's GUI. Post your poem or rap, with the aid from the rhymerator!
Here's mine:
Jus' Can't Hang
Why you gonna go and do that shit?
You ain't nothin' but a punk in a baller's outfit.
I cross you up day after day.
Open up the lane an' it becomes a freeway.
Swoosh! Like that, I'm up in the air.
Slam! Sit your ass back down in that chair.
Don't bring that And1 shit on my court.
To do the shit I do ya need a fuckin' passport.
'Cause when I fly high, up to the sky,
Your bitch ass jus' gon' sit and cry.
Cry to yo' momma, in yo' pajamas.
Seek wisdom from the Dalai Llama.
He tells you ta stop, it ain't yo' thang.
When it comes to the court, you jus' can't hang.
