A sexual act which involves crawling through sand while your partner (Male or Female) attempts to mount and ride the individual crawling through the sand. The crawling partner (henceforth known as Shai-Hulud) must continue the crawl and attempt to burrow as deep as they possibly can. Upon climax the rider must declare as loud as they possibly can that Fear is the Mind Killer and ejaculate onto the back of Shai-Hulud. The DUNE is complete when the rider licks the sweat & ejaculate off of their partner and declares themselves the king (or queen) of the Freman.
Let's sneak away during our beach tip and DUNE each other!
A grime-caked, foul smelling vagrant and/or panhandler, who has the appearance of living in a post-apocalyptic, war-torn habitat (ie—like a character from the movie, “Dune.”)
Keep your distance from that annoying Dune who lives behind the dumpsters in Chinatown! There are fleas jumping out of his nappy and filthy Dune-dreadlocks!
