To preform a "Bonwag" involves spelling ones own name incorrectly. Anyone can accidentaly pull a Bonwag, and if they do they have gained the right to be called a Bonwag. The word originated in Ireland where it has become a cultural phenomenon.
1. Dude, you spelt your own name wrong! Your such a dirty Bonwag!
2. Wow, I almost pulled a Bonwag! How retarded would I have looked!
