Havin come up with similar lines as other rappers without having heard the other rappers first I know it's possible to think of the same shyt.
We all followin the same basic logic for metaphors, wordplay, similes. I'm never surprised if rappers use a similar concept or even almost the same thing.
Could he have stole it sure, it ain't like it was that hot to steal in the first place though. Rappers always 100% sure someone stole they shyt when it's prolly 50/50 dude came up with it himself or repeated it subconsciously.
Not sayin he didn't steal but these under the radar rappers always so sure someone bit from them directly and its always some obscure random shyt or old shyt. J-Hood writes bars so I know he knows it's possible to come up with a similar line as someone else, I GUARANTEE you he has discovered a bar of his that was close to someone elses, ALL rappers have.
