A psychological and sociological phenomena whereby your friend or family member is preferred over you by some person that you know or they know. They would usually be passive aggressive to you or throw shade on you, whilst blatantly favoring and complimenting your close friend/family member. This is because they appear somewhat or relatively "nicer" or likable compared to you, even though you're not that different. A reverse effect of this also happens where you're preferred over your friend/family member. This is called a Fohn effect (or foehn effect).

"Foehn/fohn" is a weather term: when it is cold and snowy on the windward side of the mountain, whilst it is warm and sunny on the other side, the rain shadow side. In the sociological sense and analogy, you are in the shadow of that friend's favoured qualities. So that person who plays favourite doesn't see your qualities, as your friend or family member's likable characteristics overshadows yours. Hence, you are "Fohn-ed" or you had the "foehn effect".
My brother's best friend James really admires and likes my brother. He likes him so much that he dislikes me for no reason, other than he just likes my brother more. And so I pale in comparison with him. His great qualities diminish mine. I'm Foehn'd as fuck!

My sister has such a love-hate relationship with her colleague, Maureen. But usually they would argue and fight. Maureen can't stand my sister so much that I appear so likable and praiseworthy to her. This time, my sister is Fohn'd.
