A Persian last name. Derived from an arabic word meaning "the trusted one". The baddest muthaz on this planet have Motamedi as their last name. These people are usually very educated, funny, brilliant, and good looking. They also have many friends who insist on calling them by their last name. Guys who date Motamedi women want to take their GIRL's last name and have looked into how they could legally do that. Girls who date Motamedi men want to marry them just to get the name (and of course the amazingness that comes with it).
Wow! Did you just kick ass? You did! I swear you're a Motamedi. Let me see your ID.
