Rep. Alan Grayson (D-Fla.) has done it again.

Appearing on MSNBC's "Hardball" Wednesday night, the Florida Democrat used a colorful acronym to respond to Dick Cheney's criticisms of President Obama.

"You know, on the internet there's an acronym that's used to apply to situations like this. It's called 'STFU.' I don't think I can say that on the air, but I think you know what that means," Grayson said.

That acronym is short for "Shut the f**k up."

Last night, Cheney had lashed out at President Obama's decision to give Khalid Sheikh Mohammed a civilian trial in federal court.

"He'll be as important or more important than Osama bin Laden," Cheney said about the plotter of 9/11. "And we will have made it possible. We will have given him that platform, that opportunity, to come here and there is absolutely no need to do that."

Cheney also accused Obama of giving "aid and comfort to the enemy."

Grayson recalled that it was the Bush administration who was close to the Saudi royal family.

"I remember Bush Junior kissing Prince Abdullah on the cheek, and then holding his hand for an extended period of time," Grayson snapped. "Maybe if he'd let him get to second base, then gasoline would be a dollar a gallon."

The National Republican Congressional Committee (NRCC) slammed Grayson's colorful remarks.

“The foul mouthed man-child from Orlando is at it again, taking to the airwaves to bring shame to struggling Central Florida families who want jobs, not nut-jobs," said Andy Sere, spokesman for the NRCC. "But speaking of bases, Alan Grayson’s constituents surely find themselves wishing his parents had never gotten past first.”
