One of arabic descent, a tasneen is usually a girl from the saudi arabian empire. Despite her dark skin she has the tendency to grow up in the canadian tundra. The name is quite rare and relates back to the early years A.D. where a woman was "tasneened" or trampled by horses and having the vaginal fluids sucked out of her body by the horse. She is usually graceful but tends to go crazy, yelling at others while intoxicated. Happens to have a gumdrop looking nose and is horrible at giving handjobs due to an unexperienced sexual background--besides with animals which is common in the homeland.
Dude, you should've seen this girl; when she was drunk, she was tasneening all over!!
