1) Old man booze, such as Jack Daniels, Jim Beam, or any such corn whiskey or spirits.
2) Jizz, cum, spooge, spunk, man-cream, love juice, ball beverage, nut nectar, well you get the picture

1) I got grounded for a month for sneaking in the basement and drinking grandpa's cough medicine.
2) My girl had the flu, so when she was blowing me, I came in her throat and gave her some of grandpa's cough medicine, and the next morning she was fine.
