Flex Officer

A little bitch of a CO ( Correctional Officer) that is constantly found underneath the desks of his/her superiors.
The Flex Officer gets to Flex on all the other correctional officers because he/she "knows" that they are better than everyone.

"unfair".
Being a Flex Officer you will usually only do half of the job he/she is suppose to do, and expects applause from everyone.Their superiors usually consist of a Daddy Captain, Mommy Lieutenant, or Uncle Lieutenant.

Hey CO, why are you staying late?
Flex Officer said he was not allowed to be mandated.
