Be careful where you talk about Nickelback when you’re south of the border. It’s not why you think though. The US law enforcement community’s head is so far up its own arse that they may think you’re saying Nickel Sack (slang for a $50 sack of weed) and detain you. This actually happened and of course a heroic citizen caught it all on tape (see below).
This kind of tomfoolery by a local constabulary is definitely proof that you can’t fix stupid!
