SFD/MFU

Shit Flows Down, Money Flows Up

How things work. The rich get richer and the poor get the shaft.
A company goes bankrupt and everyone loses their pensions while the CEO and upper management get million dollar bonuses.

"Yeah, that's how it works, SFD/MFU."

How Tony Soprano describes the mafia. "Shit flows down, money flows up."

When two people spend a lot of time together and begin to develop feelings for each other. But they actually are just assuming society's view on relationships. That people are suppose to be in pairs. So two good friends think they're in a romantic relationship.
John and Jane are both unemployed, so they have a lot of time to spend together. They start getting feelings that they mistaken as romance. They start really dating, get jobs and realize they were suffering from societal familiarity disorder (SFD)!
