Top Definition
A type of excruciating pain affecting the entire head for several hours after listening to a selection of tracks from the derivative Canadian schlock-rock band, Nickelback.

Note: The headache can develop into a full bodyache if the person continues to subject himself to aural torture.

Possible side effects include: shopping at Wal-Mart, driving a Hummer or pickup track, loss of vision, loss of sex drive, alcoholism, and a possible desire to listen to the same song over and over and over again.
"I was driving, on my way to work, but I had to pull over and call in sick...another damn Nickelback headache..."

"At first, I thought that Staind was playing, but by the time I realized my error, it was too late, the intense throbbing and anal leakage had already begun"
