Roister is a verb that means to engage in boisterous revelry.
The Latin word rusticus (ROOS tea coos) meaning ‘rustic’ or ‘rural.’ In time, the word’s meaning shifted and roister became a verb that described the act of celebrating in a loud and boisterous way.
I can still remember all the noise and ruckus outside when the Cubs won the world series. I could hear rowdy fans roister well into the night.
