1) Unclean vagina, noticable due to the sandy residue on index and middle finger or the whole fist respectively.
2) Old virgin/female that has not been penetrated lately
3) In a pinch, it can be used for a male that hasn't gotten any lately either. Especially insulting because it also attacks their manliness
1) "Dude, do you remember who I went home last night? I woke up with my fingers all sticky and residual!" - "Oh, you poor fucker, check for STDs, you laid that dirty ol' sandcunt from the bar"
2) "Your sister is such a sandcunt, she deserves a pity fuck."
3) "Let's get Joe a drag hooker for his birthday, he's such a fucking sandcunt!!"
A shortcut taken across desert sand. This is very common in the Middle East where populations are growing faster than infrastructure, such as is the case in Dubai, United Arab Emirates.
Traffic was so bad on Emirates Road that I had to take the sandcut between Dubai and Sharjah.
