bisharaf
Persian/Farsi word for "dishonorable." Honor is an incredibly important concept in Iran, so this is one of the worst insults you can say to someone. If you call any random guy on the street bisharaf, chances are they will immediately pick a fight with you.
Behrad: Adib you're such a fucking bisharaf.
*Adib proceeds to beat the shit out of Behrad for insulting his honor*
