Pull apart the buttocks of your consenting sex partner, and as per the French greeting kiss each inner cheek from left to right whilst dragging your nose across their bumhole. Voila the dirty bonjour.
"Oh la la" exclaimed Angelique, as I bent her over and warmly welcomed her with a dirty bonjour.
Mr. Burns: Smithers, are they boo-ing me?
Smithers: Uh...no. They're saying boo-URNS, boo-URNS
Mrs. Burns: (To the crowd) Excuse me, are you saying BOO or BOOURNS?
Crowd: BOOOOOOOOOOOOOOOOOOOO!!!!!!!
Hans Moleman: (to himself) I was saying boourns.
In a billingual province such as Quebec, you have to greet people in English and in French when you work in customer service. After a while, it just becomes one word because you're so used to repeating it over and over. As well, it MUST be "bonjour" that is said first, because French (on the whole) are unforgivably uppity. And don't even THINK about just saying "hi!"
For those new in customer service;
"Bonjour, hi! Est-ce que je peut vous aidez? Can I help you?"
And after years of apathy in customer service;
"Bonjourhi. Est-ce que je peut vous aidez can I help you." (Said all in one breath)
