A term used to describe marks left on the inside of a
toilet bowl after a rather large stool has been squeezed out. It differs from 'normal'
skid marks as it leaves somewhat of a pattern, rather than just an up-and-down streak, and may sometimes resemble a
map of Africa, or any other map for that matter.
Jane: ''Harry, take a look at what someone has left in the toilet.
''Harry: ''Good
grief, I've never seen anything like that before.''
Jane: ''It's the biggest
map of Africa I've ever seen.''
