Kismesis 

This is a mash-up of the words 'Kismet' meaning 'fated' or 'destined' and 'Nemesis', which i hope we all know means 'rival' etc
so together, a Kismesis, (or plural, as in 'a pair of Kismeses' taking after the plural of nemesis) is your fated rival; or even, some would say, your Serendipitous Rival. Kismessitude is also sometimes called 'Black Romance' or 'Caliginous Romance' (calidinous meaning misty, dim; obscure, dark) in that it is dark and hateful, so lets not forget the romantic aspect, as in competing with someone so often, tensions run high... including sexual tension (eyebrow-wiggle)
now that you know what a Kismesis is, go get your black-mack on

Antithesis: Matesprit

A lot of people think that Naruto and Sasuke are in fact Kismesis, as not only do they do their best to out do each other at every turn, but they also kissed at least once.
