A beautiful Romanian woman gets on all fours, and one fills a condom with liquor (traditionally tzuika, or vodka), pinches the end, and inserts the open end of the condom into her rectum squeezing the liquor into her cavity. the inserting party then pulls the empty condom out and the beautiful Romanian woman clenches her sphincter, keeping the liquor in. as she clenches, they rub the clitoris passionately as they insert a plastic straw into the rectum, and proceeds to drink the liquor out of her rectum.

(I was taught to preform this act by a beautiful Romanian woman while on vacation in Germany after college. It was okay.)
i am hungover, because my beautiful Romanian partner suggested i drink tzuika (the national drink of Romania) out of her ass with a straw. i threw up, but it was worth it, since she loves a good old Romanian Juice Box.
