FMS

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.
