A lubricant you can use to shove fingers up your poop chute
Me- “hey green soap is so nice feeling in my butt.”
Friend- “I do love green soap!”
Defines the accepted remedy of the era, to rid one's public area of the crabs. Truly a green soap-like liquid, syrupy in character, was used to kill those little bastards. Commonly used in my own personal experience, roughly late 1950s - mid 1980s. Oldie but goodie, shouldn't lose the classics. Refers to public lice infestation, a wonderful experience to avoid.
Crap, my mom found my Green Soap, and won't let go. She wants to know where I picked up the crabs but I refuse to name your sister.
