Sorry. I beg to differ here. I need to disagree with Johannes Axner. A safeword is better to keep in another language. Also Cut is used in filmdirecting and theatre to stop a scene cause it is boring. I use words in that meaning when directing/GMing Freeforms like Anna Westerlings Growing Up (some scenes needs to be cut at times to avoid the tension just dwindling away - hah)
I guess we first need to collect all the different uses (and maybe also make a note on veils and lines from the freeformers of US to relate it to something well known to others ?)
I vote for "kutt" as the main page - although I am well aware that I have only 1 vote, like anybody else.
