scathing

In the hope of narrowing the lead amassed by Barack Obama and perpetuating a bitter democrat fracas, thousands of loyal Republicans held their collective nose and rallied to do the unthinkable -- vote for a <expletive deleted> Clinton.\r \r And was it ever successful!\r \r Just as Limbaugh, red-faced and pounding the desk with laughter, was reveling at the tumult he had single-handedly incited, several networks began broadcasting scathing, hate-filled, and anti-American sermon excerpts of Obama's mentor, the Farakahnesque black-racist bigot Jeremiah Wright of the Trinity United Church of Christ in Chicago.\r \r Then all hell broke loose.\r \r Obama, with the wheels of "hope" coming off his wagon of "change," was forced into damage-control mode to stop his plummeting poll numbers

The motivation of this type of person can usually be accurately construed as a desire to be obnoxious and offensive.\r \r Origin: The phrase "porch dog" is used to refer to dogs that sit on front porches and bark (vigorously and fruitlessly) at passersby, but who pose no physical threat. > Yeah, that guy has a scathing response to just about everyone who posts in this forum
