Since the noise about that "This is Nigeria" song is still on and so many are Yeah to the song, I think it is fair to address this post as I so did.

Henceforth, I suggest we join hands to address Nigerians as "Fellow criminals".

And you may go unique by trying Fellow lawbreaker, offender, villain, delinquent, malefactor, culprit, wrongdoer, transgressor, sinner; More
young offender, juvenile delinquent;
felon, thief, robber, armed robber, burglar, housebreaker, shoplifter, mugger, rapist, fraudster, swindler, racketeer, gunman, gangster, outlaw, bandit, terrorist, bioterrorist, narcoterrorist, ecoterrorist, cyberterrorist, agroterrorist

You can also use any of these words.
