A test that it is 100% necessary to give to all of your friends before continuing your relationships. The test must be delivered in an inquisitive tone, as to trick the friend into thinking you are also a fan of the band.
Through the administration of this test, we can successfully alienate the Nickelback-loving world, and eventually separate them from us completely in society, leading to our nationwide radio stations being freed from their reign of terror.
"Hey Nick, I just saw that there is a Nickelback concert here in June. You want to go?"
"Dude, I love Nickelback!! Let's do this!"
"Nick! You too? NOOOOOOOOOOO. That was the Nickelback test! Don't ever talk to me again."
