Sahi - סָחִי
Pronunciation: Sa·hi
Literal translation: Sober, uncool
The literal translation of sahi in Hebrew means someone that is sober, that doesn't drink or do drugs. But the word is commonly used as a slang word, to describe someone that isn't cool or fun.
Example: What do you mean you don't want to come to the party, don't be such a sahi!
