Brown treasure 

Treasure found deep in the cavernous anal region of the human wasteland. Most often brown, soft to the touch and warm with a distinct odour which some may find distasteful.

Can be used as a means to subtly convince your girlfriend that poo is a fun thing to play with.

Also known as poo.

Lynne: "why do you like my bum so much?"
