Laddergoat
To laugh so hard during sex you can’t finish. You’re just giggling like a lunatic and your partner is confused.
My mom had sex with my uncle and laughed so hard she couldn’t finish. I called her Laddergoat.
I had sex with my dog and laughed so hard I peed on the floor. I was Laddergoat.
My dad had sex with my teacher and cackled like a madman. He was Laddergoat.
