Slang from South West
England, a squitter is a thoroughly
nasty, smelly, disgusting squirt of liquid or semi-liquid faecal matter. Usually used as a plural, the squitters is an attack of diarrhoea brought on usually by overindulgence in alcoholic refreshment. Using squitter in the singular form means a
single squirt of repulsive, stinking, watery shit and by extension a repulsive, stinking, watery shit of a person. In both cases the best thing to do is flush the toilet with plenty of disinfectant.
