Once upon a time back when men were real men and lopped off heads and drank beer from the resulting skulls and bitched about the beer always dripping out of the eyesockets, one guy knew exactly what makes life worth living.
Mongol General: Conan! What is best in life?
Conan: Crush your pelvis. See her coiled around you. Hear the lamentations of women.
Mongol General: That is good! That is good.
Naturally, we can assume that Arnold was referring to the Apophis:

Arguably the queen of the snakes, sporting a venom that will never be purged from the victims body and has an effect that closely resembles snorting cocaine made out of viagra with all orifices at the same time. Will beat up Pharaos for husbands, hijack pyramids, and will love her husband until the end of time.
Best snake.
