When you've got something going for you so good (money, women, fame, power,
respect) that you become out of touch with reality and start: acting reckless, taking unnecessary risks, and get caught slipping.
Ex
1: Dude making so much money trapping that he starts to slip up and not take proper precautions.
Ex 2: Movie examples: Scarface, Paid in Full, Juice (fell in love w/ the
gun), Wolf of Wall Street, Casino, Goodfellas
Ex 3: Dennis Schroder turning down 80m from the lakers because he wanted 100-120m.
The term was coined by Gucci mane: "If a man does not have sauce, then he is
lost. But the same man can got
lost in the sauce."
Let's break down what he means. "If a man does not have sauce, then he is
lost." - with no sauce (money, women, fame, power,
respect) then what is that man living for? He's lost. "But the same man can got lost in the sauce" - too much of a good thing can be detrimental.
