1. primal, carnal urges that oppose one's reasoned judgements.
2. similar to "deep down in my heart" but more crude, and doesn't reference one's feelings of love, affection, or idealism.
3. one's wants that appeal to using things and services for pure, selfish, pleasure, regardless of consequences. (ex. sex, drugs, alcohol, fighting)

While engaging in a devil's 3-way, the males lock hands, forming an upside-down V. The female reaches around and tazes the males in the genitals if they break the upside-down deep-V.
I can't believe Tyler and Garrett wanted to do an Upside-Down Deep-V Reach-around with me. It was intense!
