you don't need to have constant multi's but its something you should try to get better, especially internal rhymes. it was stuff like this that let 8 downQuote (8Diagrams)
You can't even spread/ Peanut butter on bread/
also some of the lines were really really long you should have put a rhyme in the middle of the bar if you're gonna do it that long
Quote (8Diagrams)
The only use you have for your middle finger is stickin' it in your asshole/ But you ain't gonna get pleasure in that or anything in life, cuz your strength is so low/
its a long line and the only rhyme is at the end and even then, saying he's not gonna get pleasure from sticking his finger in his ass because his strength is low doesn't make much sense, like are you saying its because his finger is too weak to go into his ass?
or when people use common phrases, as a figure of speech such as big l's "are you broke? *boom boom* now you're DEAD broke",
internal rhymes and double syllables or mulit syllables also give it a good flow, but it takes time to work on it, i'm just saying for the future you should try working on that to get better
try listening to Big L and do what he does, if you want punchlines its good to look for words that have double meanings and make a play on that. notice big l always used multi's on his first album,
