Background: Cooking rice is a daily chore in households in Hawaii. This chore is often tasked to the children/teenagers of the family who usually got home from school before their parents and were instructed to cook the rice for dinner.

Hawaiian slang: This phrase has the equivalent effect of "go home!" or "go back to where you came from" in American speech. There are many equivalent uses: some used to express disdain, some used jokingly and some used to express relief from a hard day of work.
Ex. 1 - Mahina (at a football game): "Fuck the Huskies!! Go home cook rice!"

Ex. 2 - Leinani: "Don't even kno how fo' do simple division? Brah, you bettah just go home cook rice."

Ex. 3 - Kawika: "Ho braddah, dat one homework took so long. Finally pau. Time to go home cook rice."
