The process of masturbating and ejaculating on ones own hand, such that your freshly produced semen can now be utilized as a multi purpose lubricant for many applications such as a edgingsession, gooning session, the batter for a fresh chicken cutlet, etc.
My step mother walked in on me performing the act of squelching and my hand and penis were covered in my freshly brewed nut.
When you find the fattest chick in the bar, and take her home to dick her down. As you proceed to take off her parachute panties, you shove a apple in her mouth. And then proceed to slap her belly, over and over again. As you do this she will start to squelch. At which point you start screaming “ hear little piggy” as she tries to pull away.
“Broooooo, I need more apples man”. “ the squelchingpig is getting to expensive”.
