Symptoms include repeated ramblings such as "Calm down, Calm down" whilst dressing up in a shiny shell suit and robbing hubcaps off parked Ford Escorts. Sufferers commonly refer to their home as a scouse house. If symptoms go untreated the scouse louse disease may spread to known acquaintances or progress into rioting, grand theft auto or even muggings. The diseased are often seen eating bukkacake in public.
