abbreviation for the phrase "fuck me sideways"

Used during a time of aggression when something doesn't go according to plan, not actually as a command.

The abbreviation is generally used so parental figures don't know wtf you're saying.
Person 1: I heard you got rejected by that fly ass bitch.

Person 2: Yeah...FMS.

Stands for "fecal management system" in the hospital. It is a tube stuck up the anus of someone in the hospital if they are not capable of asking for a bedpan when they need. Used as something derogatory to call a person you don't like by hospital workers.
