Combination of WTF (What the fuck) and PWNS ('owns' in the sense of 'defeats', see: PWN). Used to describe a total victory over someone who didn't even stand a chance.
"The average gamer playing a first person shooter on a PC with keyboard and mouse wtfpwns the average gamer playing the same game on a XBox 360 with a gamepad."

Beyond simple a simple pwn, "wtfpwn" means to pwn someone in a quick and decisive manner, such that they don't know what hit them and/or have little chance to react before dying.
