An acronym for 'Fuck My Tiny Bladder' - When you realize that the traffic jam you're in will go on for another 2 hours with no toilet in sight. It's times like these you regret having that last cup-o-java before heading out and curse your tiny tank.
Guy stuck in Traffic: "Geezus wtf, we're not moving at all, why did I have that cup of coffee just before I left? FMTB"
