a moanerr is a girl that loves to have phone sex and moans really loud & fast( or asks a guy what he prefers and does it) until a guy cums. She also gets really horny from the sound of him jacking off and this may make her moan even louder if she decides to finger herself.
Guy to friend:
Dam, did you know that lisa was such a Monerr ? woahhh she was so good last night :]
