They were joking around before the game not sure there is much to this from where I sat it looked like he was just celebrating.
A few things I know and a few things I'm speculating on here.
I've watched Wade and LSU at least a dozen times this season along with the three times against Bama. Wade has been "buddy, buddy" with all of the SEC coaches. Seeing them joke around before the game, even with the crap before tip-off, doesn't shock me.
Bill Armstrong is the guy you need to pay attention to here. Wade's back is turned to Jones and Oats during that picture and it's Armstrong both are looking at here.
It was Armstrong that started with Petti before the game. It was Armstrong, as well as that team, that's been chirpy all year.
Herb was looking right at Armstrong.
Notice where the ref is in that pic? In my opinion he's hearing the same thing after the game as he did before and instead of quickly running off as they often do he stopped.
There is no love lost between Alabama's coaching staff and LSU's. Coaching staff's get pissed off when recruits are bought out from underneath them. And, you'll see them friendly with each other on game days. (See Hugh Freeze as another example.)
Talking a lot of shit is just one of LSU's cultural problems and here's one they, once again, haven't backed up.
