(There are two types of human named the matchmaker (though one is largely extinct.) , however the one I am to talk about is the one who tries to get people to fall in love NOT the one who works in a factory in Victorian England before dying of phossy jaw (the phosphorus in the matches would get in their teeth and their jaw would rot. Interbreeding with normal human males that lived near the match factory and made false teeth was largely the cause of this species extinction.) )The matchmaker has evolved primarily to continue the species as all creatures have. However the matchmaker, instead of the usual method, will seek to continue the species by finding people of their gender who are not currently in a relationship and trying to force them into one.
They work by singling out one member of the pack and herding them away from the others at which point they will point to the nearest member of the opposite gender and say “He likes you, do you like him? Do you think he’s fit? Do you want to ask him out?”
The prey will shrug as the member of the opposite gender (henceforth to be known as a MOTOG) is in earshot, denying that he was involved in this in any way. The matchmaker will take this as an expression of deep passionate love.
The hunting cry of a matchmaker is very distinct, and sounds something like this “X loves Y! X loves Y!” This immediately alerts every nearby pack within a 20 mile radius to come over and tease and annoy the victim so as to discourage the birth of pack members that may cause them to lose their place in the hierarchy.

I’m giggling really hard right now. Thanks for that.
