A girl who has macaroni and cheese nipples has abnormally
long nipples and is lactating. The milk excreted from the nip
dries around the end and oozes out uncontrollably, thus looking like
day old macaroni and cheese.
Dan: "Dude does
courtney have macaroni stuck on her chest?"
Gil:"No dude i think shes lactating. She has an extreme
case of macaroni and cheese nipples."
