pipe down~
Meaning: A signal on the bosun’s pipe to signal the end of the day, requiring lights (and smoking pipes) to be extinguished and silence from the crew. Sexual is ramming your hard cock down and all the way into a pussy / asshole or her mouth, then maybe hearing that gurgling sound for a great connection!
They always said, Plumber's were great for laying pipe down~
Example: This was always thought her hubby's friend was a Plumber, cause he would lay his pipe down and make for a tight connection without leaks!
