Used to call someone who has just had the same thought as you and expressed it verbally (or otherwise), either simultaneously or prior to you expressing it.
A term created long before Hivemind, meaning the same thing.
Phil: Think of an epic MRS moment that happened between us to use for the example.
(at the same time)
Dale: So many.
Phil: So many... lol.
Dale: Like that one.
Dale: MRS! I was going to suggest that!
(An example of a double MRS)
Strangely, "In other European languages, non-sexist usage in this regard usually amounts to using words more or less equivalent to Mrs. (madame, señora, senhora, signora, Frau, bean-uasal) for both married and unmarried women, and whether they take their husband's name or not. This makes sense as these titles are usually the direct feminine equivalents of the male titles (monsieur, señor, senhor, signore, Herr, máistir/tiarna, maighstir/tighearna), whereas the equivalent of Miss is a diminutive of the female equivalent (mademoiselle, señorita, senhorita, signorina, Fräulein, ógbhean-uasal, maighdeann-uasal)." - Wikipedia
Good for just about nothing except sex, whinging and taking your money. If the world doesnt revolve around them, then there will be hell to pay.
Guy with Mrs: Lol are you serious? The Mrs makes me buy her shit and I have to spend money on that thing that calls herself human. Otherwise, no sex. :(
Single Guy: Whoa man, I feel sorry for you. Cya :)
