A dump that is of such
impressive qualities (whether girth, length, odour or texture) that to simply flush it away would be unthinkable. It is therefore carefully transferred from the porcelain bowl to a suitable receptacle (such as a shoebox). At this stage, one can use the shoebox to
demonstrate the excellent qualities of said turd to one's partner / family / co-workers or simply people you pass in
the street.
Matt - Has anyone seen Rusty this morning? We're late for a meeting.
Dan - about
20 minutes ago. He was heading towards trap 1 with a newspaper tucked under his arm and an empty shoebox.
Matt - OK. When you see him, make sure to ask him to bring that Shoebox Special
with him to the meeting. I think it will really start the meeting off on
the right footing.
