A combination of drugs, hookers, and trampolines. You can get high in both senses of the term and have sex at the same time. What could be better?

An expert sexual maneuver in the bedroom that involves the mid-copulatory removal of a prophylactic by the male while behind the unaware female while simultaneously bellowing "BEAST MODE." It must be done in the deepest tone possible for proper execution.

The term beast mode is derived from the fact that animals and beasts do not use condoms. Therefore, if an animal or mongrel were to use a condom, they must then shout, "HUMAN MODE."
"Dude, after two months of careful planning, I finally went beast mode on Becky. It scared the shit out of her, but she went along with it for a while until she saw the condom dangling from the bedpost."
