look up any word, like sex:
a sexual act that involves first defacating without romoving fecal matter from the anus, allowing said feces to dry to a "crusty state" and then receiving a rim job from your sexual partner.
Man A "Dude did you toss that chicks salad last night?"
Man B "Yes I did but I think she might have given me a crusty lopez."
Man A "Lucky you."
