"whar" is occasional slang for people who are too lazy to fully pronounce the word what, and it comes out as sort of a mumbled "whar" noise. They also can type it this way, too. Other examples of similar ways of doing this would be wot and wut.
Jason asked a stupid question, and Ra answered him by asking "whar?" in response.

Person 3: What the fuck, you need typing practice
Person 1: guys stfu, everyone makes mistakes, I just pressed "r" instead of "t" when I spell "what"

First seen in the Family Circus parody site in which humorous captions are substituted for the normal ones; the cartoon was of Jeffy fishing and fantasizing about riding atop a giant fish that he had caught. The idea was apparently that the fish's poop was keeping it in place, and the "whar" was included to lend it a maritime flavor.
Me: Whar doon tonight? Wanna catch a movie?
My sister: I’m bust tonight! Whar doon tomorrow?
Me: I don’t care whar doon tomorrow because I wanted to hang tonight.
