To SBD or not to SBD...

OMFG....some guy one row up on the aisle seat just detonated an atomic bomb. I think by the way he was studiously looking out the window with a blush of bright red creeping up his neck that this explosion was, in fact, supposed to be an SBD....only the force of exit caused a loud squeal against the rubber of the seat that was unmistakable. I hope this poor bastard doesn't have internal damage.....
