look up any word, like blumpkin:
a. The name of a girl
b. Also known as Rahanuma or Rahnuma or Riham
c. Usually describes a beautiful, very funny, adorable, sexy girl with a great personality and a nice rack. Needless to say, guys go crazy over a rehnu
Guy 1: Did you talk to the new girl in class?
Guy 2: I did! She's such a rehnu. I WANT her!
Guy 1: Hands off! I call dibs on her. I saw her first.
Guy 2: I challenge you to a duel for her. Whoever wins, gets first shot at that rehnu!
