an existential state of uncertainty defined by transcendent, even blissful, confusion

Lost in the sauce is when you are loaded drunk, so you're a bit out of touch with reality.

When someone knows to much sauc and is on the verge of exploding ultimately exposing all of the sauc. Also can be used when someone gets their sauc intertwined or if someone is clueless, delirious, stupid or doesn't know what they are doing.

(Rare:) a term used to describe being high on marijuana

absolute confusion and uncertainty.

In over your head. Confused. Out of your comfort zone but in a positive way.

The phrase 'lost in the sauce' first appeared in the famous song 'Waving my dick in the wind' by world renowned band 'WEEN'. In which a man is trying to get back to his lover. 'Lost in the sauce' can be easily seen as being so deeply in love that you are willing to say things or carry out actions that you wouldn't normally do if you weren't so madly in love. The song features a man as a protagonist that is running from the police while trying to make it back to his lover after 97 days of not seeing them; all the while having to cross "a million miles of highway in between".
