MSR 

Monogamous sexual relationship. Take a relationship, then take away all the nagging, complaining about you not washing dishes, and so on, leaving only the mutual sexual enjoyment of one another. Similar to fuck buddies, but with the limitation to just being able to fuck that specific person.

I'm not really looking for a ltr (long term relationship), but a msr, would suit my needs perfectly.

We met up, and screwed like mice all night, she couldn't get enough, so I offered to be in a msr; now, I have all the fun of a relationship, without any hassle.

MSR 

Acronym for Mensa Shunning Ritual (MSR), in which members of Mensa exclude unwanted persons from their local groups.

He was kill-filed from the Mensa listserv in the local Mensa traditional MSR, or shunning ritual, so nobody would have to deal with him.
