1 definition by Grendelfish
The delaying and exacerbating of ones inevitable hangover by continuing a drinking session from the night before. The definition being analogous to the deferred and accumulating rollover jackpot in the UK National Lottery.
"We went out boozing on Saturday and had a double rollover. I didn't get in until Monday night and felt like death on Tuesday."
