Human intestinal worms are parasites that live in the human intestine, eat bowel content or suck blood from the intestinal wall.
Rum is a hard alcohol made from fermented sugar. This process usually includes the fermentation of the juices of the sugarcane plant, as well as of molasses and other by-products of sugar production. Rum is one of the major liquors in the world, with a history steeped in the myths of piracy, the Caribbean, and slavery.
Like you'd expect out of something made from sugarcane or molasses, rum tends to be on the sweeter side. Vodka: Pretty much anything (grapes, grains, potatoes) -> fermentation -> distilling. In making vodka, the liquid is distilled to 90%+ alcohol to remove most taste and aromas of the source material.
