inside-dong

Another word for vagina.

Coined by the Plumbing boys in their video about Avatar.

(Plumbing the Death Star is a podcsat featured on the Sanspants Radio YouTube channel, in case context is needed.
Look 'em up, they're pretty funny.)

Zammit: "You got your reproductive organ..."
Duscher: "My big ol' dong"
Zammit: "Your big ol' dong, or your INSIDE-DONG, otherwise known as a vagina."
