Freaking out

The acronym FO can stand for "freaking out." If someone tells you that you're FO, they think you're stressing out too much.

The phrase "freaking out" comes from 1960s counterculture, in which hippies and other LSD users used the term to refer to a negative reaction to their psychotropic drug of choice. From there, people began applying the term to other irrational, paranoid, or stress-related behavior.
