Living in Belgium for the last 9 months, where 2 of the 3 official languages are Dutch and French, I hear it used whenever someone is stating that they are about to go take a simple shower. To be honest, I'm not actually sure of the official definition. It seems that words get twisted and misused over time and the true definition is lost. I am trying to learn Dutch, it's my wife's first language, but I am getting more and more confused as time goes by. At least she is fluent in English, among other languages.
Opinions are like arseholes, everybody's got one.
