From the verb 'to amooch' meaning to shit with one's hat on.
An amoo is the performer of this act. Amooching across England, these people are usually persecuted in society and will often be found to have the name Alice.
Rowan: "Heard you dumped that girlfriend of yours mate"
Dingle: "Aye, found out she was one of those folk, ye know, she's a bloody amoo!!"
After nature's bellowing call has been answered, the shit (preferably long, thin, and smooth) is collected, and swiftly placed into a freezer. The end product is a 'sheezer' which is then used as a sexual toy or aid, and is said to create great pleasure.
"Our sex drive was long gone and burried, until i pulled something special out of the freezer. We now regularly use sheezers in bed, both her's and mine!"
