In a situation of intense sexual tension use the sexual tension jelly fish. It is a hand motion derived from the akward turtle and TMI turkey. To do the motion, pretend like you are scratching your cat. Wave your fingers forward and back, bending at the knuckles.

"I would never do such a thing, mate. I'm offended you would suggest it... Any baby oil in the medicine cabinet?"
