Swap the "B" for a "F" and say that word out loud and you'll understand what President Barack Obama really thinks about Republican accusations he burst out of Constitutional constraints and has gone rogue in the twilight of his presidency.
Obama used a riotous annual address to the White House Correspondents' Association dinner on Saturday to pay back political foes and rebuke journalists who erred by writing him off after the Democratic mid-term election debacle last year.
It was a performance which will delight his fans, but may cement a critique among opponents that Obama is much happier dishing out shots than taking them -- but the caustic tone of the speech fits right in with Washington's bitterly partisan political culture.
Obama, whose cutting sarcasm has introduced an edgier tone to the annual gala, lampooned attacks against him that have dogged his presidency, rebuffing claims he was arrogant, aloof and on his way out.
His zingers didn't flinch from taking on the most delicate of topics, including race -- and in a prolonged riff he enjoyed himself at the expense of candidates already lining up to take a shot at succeeding him in 2016.
In a centerpiece joke being played over and over on news shows, Obama said he had drawn up a "bucket list" of things he wanted to get done before he leaves the White House in January 2017.
