The act of excreting feces out of one's anus, especially the runny and smelly kind, causing significantdisgust to others.
Often when I eat gas station sandwiches, I have to go drop a Nickelback album in the closest dirty public restroom right after a hobo is done jerking off in it.
"Hey man you check out that new Nickelback?"
"Nah Nickelback sucks dude, screw Nickelback!"
"You ever listen to them?"
"Nope."
"Wow, you are a living and breathing example of the Nickelback Effect."
