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.
The Flex Officer can get away with almost anything... depending on how long they can hold their breath underneath that desk, and depending on how much they cry
"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.
