Clitsand
Similar to that of dicksand, but when dealing with a vagina. It's when dudes drop everything to be with their girl, who really isn't that cool or interesting in the first place. Much like quicksand, clitsand is what guys get caught in when they're obsessed with their girlfriend/crush/wife or really anyone that's giving them vagina.
Fucking Robbie, man. He fell into the clitsand--that's why he's not coming out tonight.
