This is an acronym for Dick Pics Per Match. A beautiful or slutty looking female on dating apps (Tinder and Plenty of Fish) usually has a lot of men sending them unsolicited pictures of their genitalia once they match. Depending on how many pictures a female gets will determine her DPPM rating. A DPPM score can help a woman learn where she fits in the sexual marketplace (Not to be confused with the dating marketplace). This is done in a percentage. A less than 30% DPPM rating may indicate a woman that has a wholesome presence or is unattractive in the sexual marketplace. A DPPM of 31% to 70% is your average good looking woman. A DPPM rating of over 71% will usually indicate a sexy woman or a woman who dresses (304) in a manner that welcomes unsolicited dick pics.
