Randomly yelled out across the office to the satisfaction of bakalaka usually by the gagg or the Milne factor.

The key is to yell it out at the most unsuspecting moment, it will shock and entertain those that are lucky enough to hear it.

The nooooooon part needs to be drawn out for maximum effect.
Eg.

The office is quiet everyone is hard at work then all of a sudden out of nowhere....

Gagg: Afternooooooooon ladies!

The women are startled and dont know what to think while all the men crack up laughing.

Bakalaka: Luv ya work BIG FELLA!
