Having anal sex with a group of women bent over in a circle, sticking their asses up in the air, thus resembling a shrimp ring.
"Man, that orgy was off the hook. These 6 girls all got in a circle and stuck their asses in the air, and I ass-fucked each of them. It was a regular old Singapore Shrimp Ring".
