Basically, an act of love between a consenting couple, where the male makes his female partner seriously moist, while she is still wearing knickers/thong (cotton gusset recommended). Then, remove pants/thong and either dry naturally or accellerate the process with a hair drier. While maintaining the romantic mood, scrape the dried minge goo from the pants/thong with a razor blade. Use razor blade to finulate. Roll up a bank note, and snort vaginal gold. Wait 5 minutes for an intense aphrodisiac hit. May be used as a supplement for viagra.
