An example of Multisyllabic rhymes from the first Lil Wayne song I could think of: The Sky is the Limit. (Note, this was 2 years after Tha Carter II, which many argue to be his peak)

You know I ride for my motherfunkin' niggas/ Most likely I'm gonna die with my finger on the trigger/ They tell me don't get high, and I should try to make a living/ I tell them I'm a hustler and I'd rather make a killing/ My eyes is so wide as he watching the skillet/ I let my bitch bag it, if she steal it, I'm gonna kill her/ I bulletproof the ride, now I feel like armadillas/ And fuck you, hospital, young money, we're the illest/ And I ain't gotta lie when I tell you I'm the illest/ My flow is nasty, like C Y Phyllis/ Self made G, and them bitches know the business/ Relying on rap, but in the kitchen I'm a chemist/ And when I was 5, my favorite movie was "The Gremlins"/ Ain't got shit to do with this, but I just thought that I should mention/ You looking for divine and the little intervention/ And them birds don't fly, without my permission/ I'm probably in the sky, flying with the fishes/ Or maybe in the ocean, swimming with the pigeons/ See my world is different, Like Dwayne Wade/ And if you want trouble, bitch, I want the same thing/

Some of this is hard to decipher because his accent is what makes the vowel sounds match up, and this would be a LOT easier to display if I could color code what rhymes with what. I'm not trying to tell you guys that Lil' Wayne is the best rapper alive; he's NOT. I'm just saying, the bandwagon that goes on with the internet hating Lil' Wayne is a misguided and uneducated one. He's gotten lazy and sloppy and he puts out some garbage. Rebirth was awful. But he also did some amazing stuff. Do you know who DESERVES to be made fun of constantly? Soulja Boy. Waka Flocka. People who have NEVER put out anything worth dookie. Lil Wayne has fallen from where he once was, but semi-recently 6 Foot 7 Foot was awesome.

TL;DR Lil Wayne is not as bad as everyone says, and it's easy to down-talk when you don't actually understand how much work goes into the MIDDLE of a verse and not just the last syllable of each line. Learn ya some.
