DMX is always animated, but he was extra animated from telling this story about R Kelly.
This is a 2009 interview on Shade 45, where X talks about how R Kelly wanted him to hop on a track, but when X got there Kelly was likely with a minor.
After some back and forth, X got upset because R Kelly wouldn’t talk to him face to face and in the end didn’t like X’s verse so the song was never made.
That is the very PG version of the story X told, you have to flip the page for the X-Rated (no pun intended) version of the story. I can confirm elephant penis is somehow included in the dialogue.
