an acronym for "Mouth to the Penis". made famous in the band Not Will Porter song "MTTP". Basically a term for fellatio.
Date: I don't know if i feel comfortable sleeping with you on the first date.
Dan: It's cool, you can give me a little MTTP in the back of your car and i'll still never call you again.
