What is the alcoholic drink ‘swipe’ or ‘swipes’?

"We did have ‘raising jack,’ or what we guys from Honolulu called ‘swipe,’ which was a Hawaiian word for bootleg liquor… We made our ‘swipe’ by stealing a five-gallon tin of canned peaches or plums or pineapple from the nearest ration dump, and putting a double handfull of sugar in it to help it ferment, and then leaving it out in the sun in the jungle with a piece of cheesecloth or mosquito netting over it to keep out the bugs."
