When you are fucking a woman, but both of you are kinda fat so your jelly roll is rubbing up against her muffin top, and the rhythmic undulation of humping is whipping up a frothy mixture of semen, sweat, and lube that resembles cottage cheese. You know what I'm talking about. All the juices and shit from the crotch area somehow creep up to the abdomen. I'm not a physicist-- I don't know how. All I know is that it tastes good if you use it as nacho dip.
How about me and you go out to McDonald's, grab a bite to eat, go to the movies, stop at a Wendy's on the way home, watch some Netflix, order a pizza, and end the night by whipping up some major frottage cheese.
