LOL!!!! I had that happen one time. I showed up to a birthday party with my son (a little kids party). As the afternoon and the party started to wind down and it was just about time to go, this dude starts to bring up the subject about music / rap.
I let him know who I am (in a humble way) dude reconizes and proceeds to carry on, on the subject. He then attempts to talk trash about certain Homies of mine and I cut him off letting him know they my Homies...he starts to flip flop LOL!!!! Then claims he has a album coming out in 2 months and talks about battle rapping. I'm standing there listening to him asking myself why?
He then proceeds to ask me if I know of any recording studios cause he wants to record and album...he goes back to the subject of battle raps and claims of of battled Kurupt (I think) and won. Anyhow, he proceeds to spit this high speed bilingual verse that everybody at the party looks at him like damn, this guy is pretty good (they don't know any better). I'm like "Yeah, that's tight Homie, I got to go."
Needless to say, it was a waste of my time to even listen to this dude. The people in attendance were not even credible people (they don't listen to rap), so to argue the point would be...ummmm pointless.
The high speed bilingual verse he spit was actually a verse off of T-Bone: The Last Street Preacha (a gospel rapper). I guess he thought nobody listened to that...
As drove away I was bumping T-Bone: The Last Street Preacha
