The Fiji Island party—a rager put on by Texas' Phi Gamma Delta (Fiji) chapter—is probably why Manziel's in Austin this weekend to begin with, but Manziel showing up to it in a fucking Tim Tebow Jets jersey would be one of the greatest middle fingers to expectations by an athlete of the social media era.
