Common phrase referring to one's intense desire to have sex with another, to engage in wild sex. A very strong desire to have sex with another person.
Believed to have been coined from the manner in which most engage in sex, which is with one on top of the other.
In most instances, it also indicates a desire for much more than just a quick exchange, implying a far more intensive session of sex.
Further implies a sense of impatience, of urgency, as though the person can barely contain themselves.
Used as a form of compliment, indicating how desirable, as well as good looking the other is.
