"Where It Says"

People have habits of adding some word at the end of their sentences. Normally it's 'lah' for Malaysians - "Pegi- lah!", "I'm not eating today-lah", "Working-lah". For my boss, it's "where-it-says". She'd go, "You can write anything, where-it-says". "It's a big company with various activities, where-it-says." "You can write about food, where-it-says."

I wonder how she derived this.
