A female being so fit that her undies have gaps on each side of them when looking directly down at them.
I went to the beach and this girl in a bikini had a Poon dune!
Get the Poon dune mug.
A crusty poon owned by the infamous "Dune" who is the gatekeeper of her domain. This so called "Dune" occasionally offers drunken parties where people go to trash her house and insult her poon. Not to be confused with Dune's All You Can Eat Fish Buffet.
Tyreece's friday night plans included a quick stop at the seven eleven for a big gulp followed by an enexpected encounter with Dune's Poon. On arrival he quickly realised that Dune's Poon had been trashed. Tyreece was extremely dissapointed!
