So I'm figuring when you write you get a bank of all the rhyming words you can think of, either mentally or write it down right? Just try to practice thinking how each of the rhymes can relate to one another. Take it one line at a time but think "hmmm... I got the words 'grateful' and 'faithful' ... how do these relate...." and try to come up with something like "maybe I ain't too grateful / cause I'm having a real hard time staying faithful" and bam now you painted a small picture, about a broken relationship, that you can build off of. Okay next word.... idk "anal"... any word that rhymes just try to find a way to relate it "maybe if you was down to do anal, you said it's too painful"
Lol I'm just fukking around I don't really like rhyming words with the same suffix... but you get the gist, just practice relating rhyming words to eachother. A lot of people think the hardest part of rapping is rhyming right, but it's really all the other words in between that makes a great rapper.
Edit: Maybe I ain't too grateful / I'm having a real hard time just staying faithful / It ain't all my fault, you was never down to do anal / Said it was too painful, now I'm the A-hole? I ain't no, half-steppin punk that you think you can play Ho.
lol idk
