The act of draping sheets of toilet paper between the toilet seat and toilet bowl until one has created a net in which to catch one's poop so that no defecation sound ("poop plunk") is audible to potential boyfriends sitting in the other room.
roommate A: "hey, we're out of toilet paper again, and the toilet is horribly clogged, whats up with that?" roommate B: "oh, that must be Tanya. She can't go unless she's nesting."
