"We heard later through the grapevine that we were being compared to the Furious 5, and because of that we were getting feedback that they were saying that we werent all that, that we were copying them... blah blah blah"

In this quote, Kool Moe Dee is reflecting on a time when his group, the Treacherous Three, was being compared to another popular group, the Furious 5. He discusses that they heard through reports or chatter (the grapevine) that individuals were saying they were not as gifted or initial as the Furious 5. This comparison and unfavorable feedback may have been painful and discouraging for Kool Moe Dee and his group, as they felt they were being accused of copying the Furious 5. The expression "blah blah blah" at the end suggests that Kool Moe Dee is dismissing the unfavorable remarks and focusing on his own success and talent.
