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*
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
