Itโs a line form the first chapter of Fran Bo where youโre talking to what appears to be a 5 year old girl telling Fran that when she gets her crayons taken away she scratches herself until she bleeds but because the girl is five she doesnโt know what blood is so she calls it โthe red milkโ The reason youโre talking to her is because youโre in a mental asylum trying to escape and by giving her band-aids to stop โthe red milkโ sheโll give you a crayon which helps you escape
calm down we get it you have a dirty mind
