The urban dictionary says it's a female's name for 'moonlight' but there are many males who use it as well. A person cannot be named Mahtab unless he's "fair" enough to justify it. And the person named Mahtab is a great guy to chat with but too silent IRL. As you wait to see the moon at night, Mahtab is also known for staying active at night ONLY. He sleeps in the daytime. Mahtab is well-known for everything he does. If you find a Mahtab around, please do approach him (except for the purpose of talking, he doesn't talk a lot).
Recently, a girl was found simping for a guy named Mahtab.
