Sauce is confidence. Meat is the people around you who give you false confidence (no meat just sauce). You can sprinkle sauce to others. You aren't born with confidence, you learn it (becoming seasoned). You can become over confident and lose your humility (getting lost in the sauce). You don't need money to be confident. The sauce gets you money but getting lost in the sauce will get you caught up.

The sauce is an undefinable personality trait that some women possess. It could best be described as sexual confidence, or flirtyness, but it's not quite either. Everyone knows it exsists, but no one really has a name for it, hence the name.

The sauce is very important. As Sizzles law of attraction states: a physically attractive woman who has no sauce, is less attractive than a physically less attractive woman with the sauce.

For an analogy: You could have some of the best egg noodles with no sauce, but they won't be nearly as good as some ramen noodles with awesome sauce on them.
