DM Theory 

When a girl feels threatened by another girl based on looks or personality, she will often come to the conclusion in her own mind that she is a whore, and then will tell everyone that such girl who is rich in looks and/or personality is a whore because of jealously

Mel: I can't stand that Blake is talking to Shanna she is such a whore!!
Dylan: Do you have any proof of this or are you just saying it????
Mel: I don't have to explain myself.
Dylan: Maybe you just feel threatened by her and prove the DM Theory.
