$11 -- PP Level 2, JJ : Call the push reraise from tilty LAG?

[Fergdog]

SB had been involved in tons of hands, pushing TPTK L1, calling pushes, and had just suffered a nasty beat with a flopped flush that he slowplayed getting sucked out on by a guy with 72o who made his boat. I would think he's probably on tilt, from his angry chat. Even so, he's pushing over a raise and a reraise, call?
