Cuntsludge

When someone has been pantywaste for so long that the pantywaste builds up to a pile or mountain of sludge

Girl, you just graduated from pantywaste to cuntsludge!

Cunt chuckles

Like Chuckles the Clown, but the person is a Cunt. So, Chuckles The Cunt, or Cunt Chuckles.

"Chuckles the Cunt" or "Chuckles" for short.

"Hey, Chuckles (the Cunt)!!!"
Hey, Cunt Chuckles!

Hey Chuckles!
