According to In Flex We Trust, Jay Electronica randomly started dishing out who he thinks is a good artist in the music industry, and who he doesn't vibe with on Twitter.  The expression of his thoughts lead to him commenting on 50 Cent and how much he doesn't like his music.  Jay took things to a hostile level when he started aggressively tweeting about how he wishes 50 would try and say something to him.

The tweets in question have since been deleted, but you can still see them above.
