What did John McCain say to Young Jeezy?

New York Magazine had a hilarious caption for this video, from the end of last weekend's SNL finale:

It took the closing seconds of this weekend's actually pretty funny season finale of Saturday Night Live to finally bring these two titans together, one the Republican nominee for president, the other a crack rapper of platinum sales and dubious lyrical ability. John McCain was there for a spot on "Weekend Update," and Young Jeezy came to do his verse of musical guest Usher's "Love in This Club," but, happily, both appeared onstage together during host Steve Carell's signoff. After the senator finishes speaking to Usher, (around the twenty-second mark), he turns, pats Jeezy on the stomach, and says something — but what? "I love that song 'Go Getta'"? "How are things in the trap these days?" "I have to be leaving, but I won't let that come between us, okay?" Sadly, the world may never know.
