Sauce is used to describe someone who has a style, confidence and attraction about them. Usually someone who is well-dressed, fashionable, and has an aura about them. swagger style

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.
