It’s very funny and actually very believable that this was an accident. Look down at your keyboard and think about it; the key for letter ‘B’ is right next door to the key for letter ‘N’. Many is the time I’ve had a fatfinger problem and struck one key instead of what I wanted. It’s still funny, mostly because the very idea is outrageous to put in print and the grammar is terribly off kilter, even for American English.
MY GOD! I just typed n....r in gmail to see if it came up as a misspelled word. It didn’t!
wow.
