Short for "mental shift." This is a term therianthropes and otherkin who wish to make excuses for their sometimes bizarre and animalistic behavior use to avoid taking responsibility for their actions; they believe that by claiming that they've "mentally shifted" into their spirit's supposed true form that they should receive pity no matter what they do.
I didn't mean to go on a murderous rampage on the full moon. Please excuse me: I m-shifted into a werewolf mentality and I couldn't help myself!
