“I think he’s exaggerating his threat of violence so that when Iran does agree it makes it look like it was his threats instead of anything else. Could be wrong, but I have a feeling he’s trying to just fluff up his game when he knows a deal is most likely going to be signed.”

Flub up is an informal slang phrase meaning to make a mistake, botch something, or mess up — to execute something poorly through clumsiness or misjudgement. A variant of 'flub' (to bungle or blunder), the 'up' adds an intensifying particle that is characteristic of American verbal compounds ('mess up,' 'screw up,' 'foul up'). Register is informal and mildly self-deprecating; it describes a mistake without the harshness of 'screw up' and with less profanity than 'fuck up.'
