The Silver-Back Gorilla

When two sexual partners engage in doggy style in a walk in freezer. When the man is about to ejaculate he pulls out and discharges over the female's back and rubs it in. This will cause the woman to exclaim 'ooo, ooo' like a gorilla due to the extreme sudden heating of the woman's back during said ejaculation. For added realism the man may beat his chest at the point of orgasm,remove pubic hairs and sprinkle on semen or make an African American individual the sexual partner.

Hey babe, wanna have the sexy time?

Only if we do The Silver-Back Gorilla.

back-pocket knowledge

Knowledge that one knows but only brings up when the situation presents itself.

Johnny knew he wouldn't need to know that in english, "mis bolas son picazón",means "my balls are itchy", but he remembered it just for the sake of back-pocket knowledge.
