refighe: friend
rah: road, path
when two friends start a journey (not only travelling, starting anything) together,,, then they consider each other az refighe rah, someone who will stay till the end of the journey, if he leaves, then he will be called "refighe nime rah" a "half path friend"
it can be used for betrayers as well
* mokhlesam (مخلصم) means im mokhles, mokhles means SINCERE , DEVOTEE which comes from the word "ekhlas" SINCERITY which is an arabic word

btw: instead of the arabic word moteshakeram you can use the parsi word sepasgozaram

its harder but pure and formal
