President Obama and George Stephanopoulos disagreed on what actually defined a tax increase in a feisty exchange on ABC’s This Week, causing the host to pull out the Merriam-Webster dictionary definition of taxes.

Stephanopoulos pressed the president on his health care plan in the interview airing Sunday morning, specifically on the individual mandate—which essentially forces people to buy health insurance.

Asked how that could not be considered a hike, Stephanopoulos inquired, "Under this mandate, the government is forcing people to spend money, fining you if you don't.  How is that not a tax?"

President Obama responded “ No, but -- but, George, you -- you can't just make up that language and decide that that's called a tax increase.”  Stephanopoulos then gave the dictionary definition – “I don't think I'm making it up.  Merriam- Webster's dictionary:  Tax, "a charge, usually of money, imposed by authority on persons or property for public purposes."

Mr. Obama rejected the notion it was a tax increase and said pulling the dictionary out meant the host was “stretching” a little.    He said, “No.  That -- that's not true, George.  The -- for us to say that you've got to take a responsibility to get health insurance is absolutely not a tax increase.”

You can read the full exchange for yourself after the jump.

STEPHANOPOULOS:  How about the matter of first principles, though?  You mentioned these premium increases.

OBAMA:  Yes.

STEPHANOPOULOS:  But they're not happening as a result of a decision by the government.

OBAMA:  Right.

STEPHANOPOULOS:  You were against the individual mandate...

OBAMA:  Yes.

STEPHANOPOULOS:  ... during the campaign.  Under this mandate, the government is forcing people to spend money, fining you if you don't.  How is that not a tax?

 OBAMA:  Well, hold on a second, George.  Here -- here's what's happening.  You and I are both paying $900 bucks on average -- our families -- in higher premiums because of uncompensated care.  Now, what I've said is that, if you can't afford health insurance, you certainly shouldn't be punished for that.  That's just piling on.

OBAMA:  If, on the other hand, we're giving tax credits -- we've set up an exchange, you are now part of a big pool, we've driven down the costs, we've done everything we can, and you actually can afford health insurance, but you've just decided, "You know what?  I want to take my chances," and then you get hit by a bus, and you and I have to pay for the emergency room care, that's...

STEPHANOPOULOS:  That may be, but it's still a tax increase.

   OBAMA:  No.  That -- that's not true, George.  The -- for us to say that you've got to take a responsibility to get health insurance is absolutely not a tax increase.

What it's saying is, is that we're not going to have other people carrying your burdens for you any more than the fact that right now everybody in America, just about, has to get auto insurance.  Nobody considers that a tax increase.  People say to themselves, that is a fair way to make sure that, if you hit my car, that I'm not covering all the costs.

   STEPHANOPOULOS:  But it may be fair, it may be good public policy...

   OBAMA:  No, but -- but, George, you -- you can't just make up that language and decide that that's called a tax increase.  Any -- if I -- if I say that right now your premiums are going to be going up by 5 percent or 8 percent or 10 percent next year, and you say, "Well, that's not a tax increase," but, on the other hand, if I say that I don't want to have to pay for you not carrying coverage, even after I give you tax credits that make it affordable, then...

   STEPHANOPOULOS:  I -- I don't think I'm making it up.  Merriam- Webster's dictionary:  Tax, "a charge, usually of money, imposed by authority on persons or property for public purposes."

   OBAMA:  George, the fact that you looked up Merriam's dictionary, the definition of tax increase, indicates to me that you're stretching a little bit right now.  Otherwise, you wouldn't have gone to the dictionary to check on the definition.  I mean, what...

   STEPHANOPOULOS:  Well, no, but...

   OBAMA:  ... if what you're saying is...

   STEPHANOPOULOS:  I wanted to check for myself.  But your critics say it is a tax increase.

   OBAMA:  My critics say everything is a tax increase.  My critics say that I'm taking over every sector of the economy.  You know that. Look, we can have a legitimate debate about whether or not we're going to have an individual mandate or not, but...

   STEPHANOPOULOS:  But you reject that it's a tax increase?

   OBAMA:  I absolutely reject that notion.

STEPHANOPOULOS:  Let's go to Medicare, then...

OBAMA:  Good.

STEPHANOPOULOS:  ... because you also said that no one will lose what they have.  And Senator Bill Nelson, a Democrat, says that the cuts you're looking at in the Medicare Advantage program...

OBAMA:  Right.
