A Cornish hen is when both partners spread their cheeks apart and press their butts together. One partner transfers fecal matter into the other partner, and vice versa until all the starting person has not only their own feces transferred back into themselves, they also have their partners feces inside them as well. You then baste the hen put it in the oven, or in actual terms, bust a nut on the stuffed bird and put them in the sun. It's called a Cornish hen because it resembles stuffing a Cornish hen before putting it in the oven.

A sexual position, similar to the missionary position, for very plain looking people having very plain sex. Little to no movement is involved.

The female lies on her back with her knees slightly raised towards her mid section, with her arms by her sides. Lying alone, she resembles a pre-cooked cornish hen. The man then rests his slightly overweight body between her legs and patiently thrusts into her.
